          • Tunable Diode Lasers

          • Tunable, single-frequency lasers not only for quantum technologies
            Tunable single-frequency diode lasers utilize a laser diode and a frequency selective element like a grating for laser frequency selection and tuning. They are available for individual wavelengths between 190 nm and 4000 nm, and deliver narrow-linewidth emission that is tunable – in some systems up to 120 nm wide without a single mode-hop.

            Such lasers can be amplified either in stand-alone amplifiers or in complete Master Oscillator Power Amplifer (MOPA) systems to reach CW powers up to 4 W. Most of TOPTICAs amplified systems utilize tapered amplifiers.

            Frequency-converted lasers extend the accessible spectral range in the UV, visible and mid-IR, and provide highest output powers.

            Important properties of all these systems are low noise (RIN and linewidth) and drift. Properties that profit from excellent laser driving electronics. For further stabilization, a range of laser locking electronics serves for linewidths down to the 1 Hz level and convenient digital control.
              • ECDL / DFB Lasers

              • External cavity and distributed-feedback diode lasers
                Tunable single-frequency diode lasers consist of a laser diode and a frequency selective element like a grating, which controls the emission frequency. TOPTICA offers diode laser systems with an external grating (ECDL) as well as systems with a frequency-selective element integrated within the semiconductor structure itself (DFB diodes). These systems are available for individual wavelengths and provide tunable, narrow-linewidth emission.

                    • Laser Driving Electronics

                    • Digital and analog modules
                      Apart from a well-engineered optomechanical design and the integrated laser diode, the most important part of a tunable diode laser system is its driving electronics, which is responsible for getting the most out of a laser system.

                      Wide mode-hop-free tuning with Littrow setups requires a well-defined interplay between piezo actuator and current driver. Drifts of the laser diode current, the temperature or the piezo voltage determine the drift of the laser frequency and the stability against mode-hopping. Noise on any of these outputs increases the laser linewidth. The digital DLC pro represents the latest stage of development of laser control electronics. Its noise and drift properties are even better than the well established and widely used preceeding electronics SYS DC 110.

To reduce remaining frequency fluctuations or cancel out long-term frequency drifts, active frequency stabilization, or "locking", is required.
                        • Picosecond / Femtosecond Fiber Lasers

                        • Next generation ultrafast fiber lasers for science and industry
                          Ultrafast technology has seen an unpredictable success ever since it was introduced. Many promising applications have emerged benefiting mainly from the high peak power and ultrashort pulse duration which give rise to nonlinear effects and open new paths in engineering and scientific research.

                          The key for successful integration of ultrafast technology are robust, cost-effective systems with simple push-button operation. TOPTICA offers several products fulfilling these requirements: ultrafast fiber lasers based on Erbium (Er) and Ytterbium (Yb) like the FemtoFiber smart, FemtoFiber pro, FemtoFiber ultra and FemtoFiber dichro series. All these systems are based on TOPTICA FemtoFiber technology.

                          TOPTICA’s FemtoFiber lasers provide reliable femtosecond / picoseconds pulses based on polarization-maintaining fibers and SAM mode-locking. Different models (1560/780 nm, VIS/NIR tunable output, IR/NIR supercontinuum, short-pulse) cover a wide range of applications, e.g. non-linear microscopy, two-photon polymerization, time-domain Terahertz, attoscience, and as seed lasers.

                              The FemtoFiber pro is the successor of our proven FemtoFiber Scientific (FFS). The FemtoFiber pro includes a different mode-locking mechanism based on saturable absorber mirrors (SAM) and the use of only polarization maintaining (PM) fibers. Both novelties increase the robustness and reliability of the fiber laser even further. The FemtoFiber pro is available with fundamental output at 1560 nm (FemtoFiber pro IR) and also with second harmonic output at 780 nm (FemtoFiber pro NIR). The latter system versions are integrated in the same housing as the laser with a footprint of only A4. Another system version in the same housing is the generation of a supercontinuum which spans more than an octave in the frequency domain (FemtoFiber pro SCIR). The combination of high pulse energies with very short pulse widths gives the highest peak powers on the market (regarding Erbium doped fiber lasers). The FemtoFiber pro IRS adds a powerful short-pulse model at the fundamental wavelength (1560 nm) and the FemtoFiber pro SCYb provides more than 500 mW at 1030 nm with < 100 fs pulse duration.

                              The FemtoFiber ultra series is TOPTICA's third generation of ultrafast fiber lasers. These lasers provide powerful femtosecond pulses with a ultra-high reliability. The systems use SESAM-mode locked ring fiber oscillators (patented design), followed by a high-power fiber amplifier. For reaching highest reliability levels, only polarization-maintaining fibers are used. All of this is integrated in a unit with a footprint of 25 x 38 cm². The laser systems are easily controlled via Ethernet or USB. A simple graphics user interface (GUI) enables user-friendly access to all laser parameters.

                              The FemtoFiber ultra series shares the advantages of TOPTICA’s previous ultrafast fiber laser generations. The systems are compact lasers that work reliably after a push-button start. No water-cooling is required since simple air-cooling is sufficient for stable operation. These cost-effective and compact laser solutions provide femtosecond pulses with high average power and excellent beam quality. They are great solutions for applications in nonlinear microscopy like effective two-photon excitation of fluorescent proteins and SHG based contrast mechanisms.

                            • Versatile two-color femtosecond laser systems
                              The new FemtoFiber dichro series simultaneously generates two perfectly synchronized laser beams at different wavelengths. This new concept provides a compact and easy-to-use laser system which requires no more than the push of a button for laser operation.

                              TOPTICA’s first laser system based on this novel platform is the FemtoFiber dichro midIR, which uses this new approach to generate a broadband mid-infrared spectrum. The Er-doped fiber laser based system provides broadband laser pulses that are tunable in the range of 5 - 15 μm. The mid-infrared pulses are generated in a difference frequency process (DFG) between a 1.5 μm fundamental source, and a 1.7 - 2 μm supercontinuum source.

                              To meet the broad range of requirements, the FemtoFiber product line is designed with maximum flexibility and compatibility, which enables the design of complex systems and highly customized solutions.

                              The key behind TOPTICA’s fiber laser technology is the possibility to link different laser amplifiers to a common master oscillator. The optical parameters of each amplifier can be entirely customized regarding wavelength, spectral width, pulse duration, output power, and repetition rate. With that tailored, phase-locked femtosecond laser pulse trains can be generated that are synchronized to one another with attosecond precision. TOPTICA has now expanded its capabilities by introducing a dedicated department for highly customized solutions that provides tailored fiber laser systems for novel applications in ultrafast optics.

                            TOPTICA provides complete systems and components for both time-domain and frequency-domain terahertz generation. For time-domain applications, the TeraFlash pro sets new standards in terms of dynamic range, bandwidth and measurement speed. Combining TOPTICA’s FemtoFiber smart laser technology with state-of-the-art InGaAs antennas, the system achieves a peak dynamic range of more than 90 dB and a bandwidth greater than 5 THz. The Imaging Extension enables researchers to exploit the full potential that the combination of time-domain imaging and spectroscopy has to offer.

                            The new TeraFlash smart uses two synchronized femtosecond lasers and a proprietary scanning scheme (electronically controlled optical sampling, ECOPS) to achieve extremely high measurement speeds: the system acquires up to 1600 complete pulse traces per second.

Determining the phase requires a modulation of the optical path length, or the terahertz frequency. The Phase Modulation Package offers a particularly fast and accurate technique to scan the terahertz phase, by using a symmetric setup with two fiber stretchers wound around piezo actuators. Users can thus retrieve full information on phase and amplitude of the terahertz wave - with single-Megahertz resolution!

                                      • Data filtering in both time-domain and frequency-domain possible

                                      An accessory to the TeraFlash pro, the Imaging Extension utilizes two precise linear stages to scan a sample through the focus of the terahertz beam. The translational movement is synchronized with the shaker of the TeraFlash pro, resulting in a high measurement speed of up to 16 pixel/sec. A “basic” setup is available for researchers who wish to use their own optical components, and a “complete” version includes parabolic mirrors for beam shaping and focusing.

                                      • Spectral bandwidth: 3 THz single-shot, 4 THz in 1 s

                                      TOPTICA’s TeraFlash smart utilizes a proprietary scheme dubbed ECOPS ("electronically controlled optical sampling"). The system comprises two synchronized femtosecond lasers, eliminating the need for a mechanical delay. This results in extremely high measurement speeds: the TeraFlash smart acquires 1600 complete terahertz waveforms per second, enabling terahertz-based thickness gauging at unprecedented speed. The system thus lends itself to measurements on rapidly moving samples, e.g. conveyor belts, papermaking machines, or extrusion lines.

                                      The TeraSpeed serves applications in quality control and process monitoring that require no spectral information, but call for terahertz intensity measurements at “extreme” speeds: the system is capable of detecting individual terahertz pulses at repetition rates as high as 100 MHz. An integrated data-processing unit converts the detected pulses to RMS values, enabling data streams at sampling rates up to 500 kHz – orders of magnitude faster than conventional terahertz systems. Bringing together several cutting-edge technologies, the TeraSpeed takes advantage of mature fiber laser technology, powerful photoconductive emitters and fast yet sensitive Schottky receivers.

The PFD RF input is designed for use with the RF output signal of the DFC MD. The error signal generated by the PFD is fed to the input of the FALC 110 regulator. The main output of the FALC is passed through the PFD to allow for remote switching of the fast feedback loop which modulates the laser diode current. A copy of the error signal (mon. out) is used to close the slow feedback loop acting on the DL pro piezo (Fine In) with the all-digital PID of the DLC pro. Slow and fast feedback loop can be enabled and disabled with a push of a button in the DFC user interface (TOPAS DFC)

                                    • Multi-Laser Engines

                                    • Fully Featured Multi-Color Engines
                                      The iChrome family of multi-laser engines addresses the need for lasers with multiple colors in biophotonics (microscopy, cytometry, DNA sequencing etc.) and metrology (scatterometry, ellipsometry). These applications require a flexible laser source that provides several wavelengths from one optical fiber. The compact and reliable iChrome systems thus replace cumbersome and maintenance-intensive “breadboard solutions”.

                                      With TOPTICA’s proprietary COOLAC-technology all integrated lasers can be perfectly aligned with just one push of a button. The light engine can provide up to eight different wavelengths from ultraviolett to infrared wavelengths. The individual lasers are efficiently combined and delivered via single-mode, polarization-maintaining fibers.

                                      With microprocessor-control the iChrome systems enable flexible OEM integration. High speed analog and digital modulation allows for fast switching of laser wavelengths in arbitrary patterns for complex experiments. In addition, the system provides high-end features like direct modulation (no external AOM/AOTF* required), “complete-off” and speckle management, which all can be conveniently controlled via one electrical interface.

                                      TOPTICA's iChrome family thus offers all the features and the necessary flexibility to address even challenging imaging and measurement techniques, either as standalone multi-laser source or fully integrated into existing instruments. At the same time, the system offers easy and convenient operation for beginners and experienced users as well as “no-screwdriver” installation and alignment.

                                            The research grade tunable diode laser system DLC TA-FHG pro is an ideal laser for test experiments in scientific or laboratory-like industrial environment (e.g. clean room). While not yet fully designed for 24/7 hands-off operation it comes very close to that. The DLC TA-FHG pro shows excellent passive stability due to patented and proprietary technology as well as a laser head manufactured from a solid metal block.

                                              TOPTICA provides a selection of Photonicals – Photonic Tools and Accessories. These are just as important as the laser itself. A modern optical laboratory needs analysis and measurement tools to prepare the laser beam in the requested shape, control its spectral performance, separate it from undesired feedback, etc. TOPTICA offers a variety of accessories to complement your laser source — equipment that in the daily operation of diode lasers is more than useful.
                                            • Laser Diodes

                                            • Specify your wavelength – TOPTICA can provide it
                                              TOPTICA offers a large variety of wavelength-selected single-mode laser diodes. Among more standard laser diodes you will also find "rarities", i.e. diodes with output wavelengths that only TOPTICA provides. The diodes can be purchased separately. In addition TOPTICA can integrate any diode from the stock lists into a tunable diode laser system: Fabry-Perot or AR-coated laser diodes may be integrated into a diode laser systems, DFB/DBR laser diodes into a DFB pro and Tapered Amplifier into an TA system.

                                              Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet. In case you can still not match your wavelength of choice, contact TOPTICA – and chances are very high that we can provide it within very short time.
