      • Sapphire material

      • Synthetic single-crystal sapphire (Al2O3) is the leading material for highly advanced optical applications due to a unique combination of excellent optical, physical and chemical properties. It is transparent over a wide range of wavelengths from vacuum ultraviolet to infrared regions (from 0.18 µm to 6 µm). Due to its hexagonal crystalline structure, sapphire shows anisotropic behaviour in its optical and physical properties. Therefore the exact characteristics of optical components made from sapphire depend on the crystallographic direction relative to the optical axis (C-axis, 0001). Sapphire possesses birefringence on all directions except for the c-axis. Sapphire is the hardest among all oxide crystals. Due to its extreme surface hardness, sapphire can be scratched by only a few substances (for example, diamond and boron nitride). It's great strength allows for the production of much thinner optical windows compared to other materials. Yet another reason to employ sapphire at wavelengths close to the transmission limit.

        We can deliver the Sapphire material produced by two different methods of sapphire growth:

        Kyropoulos method: is used to produce a large boule of sapphire, typically of a cylindrical form. Grown boule can be from 70 up to 300 mm in diameter and up to 250 mm in height. Sapphire grown by this method normally has a very high optical quality with low defect density with efficient costs, and can be cut into wafers of any crystallographic orientation. This method is applied for manufacturing substrates for blue LEDs and SOS wafers.

        Stepanov method (EFG): a shaped growth technique used for growing sapphire in near-net finished shape, including tubes, rods, sheets, and fibers. This technique can also provide unique shapes and sealed assemblies. By Stepanov method, ribbon crystals up to 500 mm long and 80 mm wide are grown. Crystals grown by this method can have different crystallographic orientations (A, R, random) and are mainly used for industrial & mechanical applications, where good optical qualities are not important.
          • Main applications of sapphire

              • Optical application

              • Sapphire is a superior material for highly sophisticated optical applications, because it is highly transparent at wavelengths of light between 0.18 µm to 5.5 µm , as well as being five times stronger than glass. High optical transmission of sapphire combined with the perfect chemical durability, wear resistance and the ability to withstand high temperatures made sapphire the leading material for sensor optics and optical components for spectroscopy.
              • Mechanical application

              • Sapphire is wide used for scratch proof windows in high quality watches, scanner applications and other high wear applications and for precision mechanical components, because its extreme hardness makes the surface resistant to scratching.
              • High temperature and pressure application

              • Sapphire has a unique combination of physical, chemical and optical properties allowing it to withstand high pressure and thermal shock. Sapphire has a melting point of over 2000 C°, making it ideal for high-temperature applications. High pressure sapphire tubes and windows, high strength and vacuum windows, high temperature sapphire windows are small part of large range of optics in this specific field.
              • Chemical application

              • Chemically inert to common acids and alkali at temperatures up to 1000 °C, sapphire tubes, crucibles and other sapphire optics are irreplaceable for different applications for chemical industry. Sapphire is excellent for sprays and nozzles of all types, products subjected to high temperatures or in contact with acids. Sapphire replaced quartz ware to improve durability and reduce contamination while offering good UV transmission.
              • Electrical application

              • Due to its a high, stable dielectric constant, sapphire is wide used for electronic substrates. Electrical properties of sapphire are depend on crystallographic orientation. In addition, sapphire wafers are used in the semiconductor industry as a substrate for the growth of gallium nitride based devices LED (light emitting diodes).
              • Medical application

              • Sapphire is often used in endoscopes lenses due to its durability in contact with tissues and in sterilization environments such as autoclaving. Also tips from sapphire are very good for various surgical laser applications and sapphire light guides are commonly used in cosmetic skin procedures.

                    Cavity flow tubes (monoblocks), built as one solid optical element, usually combine and perform the function of laser pump chamber, flow tube, filter and reflector. A flow tube is machined out of a block or rod of carefully selected high optical quality Quartz glass material, undoped or doped with the appropriate rare earth or metal ions. We use chemical and electro-chemical coatings with Silver and Copper or other layers to generate the reflector surface.

                    Special reflectors for diode pumped lasers
                    Specular reflectors for diode pumped lasers consist of fused silica quartz or sapphire tubes, the external surface of which is covered with silver (high reflection Ag) coating with protecting layers. Several areas of this reflector are open as a window for diode pumping. This kind of reflectors would be produced with required window sizes and configuration in accordance with the customer’s requirements.
                • Laser

                • Impex HighTech GmbH offers a complete range of laser systems from q-switched high energy to very stable single frequency continuous wave diode pumped solid state laser at different wavelength. We can offer custom specific parameters depending on the integrated bonded crystal. The adhesive free diffusion bonding is highly reliable and causes very low intra cavity losses at the bonding interface. Therefore these laser are highly reliable and sought after in industry and research.

                  By designing these lasers, the low cost, compactness, resistance against mechanical stress and flexibility of the laser was our major concern. Where high pulse intensities are needed, especially for mobile applications in different fields. For example in Laser Induced Breakdown Spectroscopy (LIBS), marking, micro machining, photonic crystal fiber pumping (super continuum generation), Lidar, range finding and as seeding master oscillator for high power solide state lasers.
                    • ELM1064

                    • These passively q-switched µ-chip lasers are all based on our own bonded laser chip. A selection of these chips (which vary in terms of length, output coupling and initial transmission) make up the base of our product lines. The main is the ELM1064, which is available in a high energy version above 210 µJ pulse energy and repetition rates of a few kHz and a in low energy version (above 70 µJ / tens of kHz). The ELM1064 generates pulse energies above 70 µJ and repetition rates of 20 kHz can easily be reached.

                      All lasers come with a computer control software for remote control of the laser and all temperature settings. The pulse width is always below 5 ns. These ELM1064 Lasers are well suited for LIDAR (light detection and ranging), LIBS (Laser Induced Breakdown Spectroscopy) and for super continuum generation with the use of a photonic crystal fiber (PCF). More details can be found in the corresponding PDF datasheets. For different specifications, please contact us directly.
                    • ELM532

                    • Our passively q-switched ELM532 lasers are just a few cm longer than the well known ELM1064 lasers. The frequency doubling of the Nd:YAG laser is done with state of the art walk off compensation which leads to a conversion efficiency of more than 50% by just single pass through a non linear crystal. These ELM532 Lasers are well suited for LIDAR (light detection and ranging) as well as LIBS (Laser Induced Breakdown Spectroscopy) applications. We reached output powers up to 500 mW, but here you will receive a much stronger pulse to pulse timing jitter. More details can be found in the corresponding datasheets below. For different specifications, please contact us directly. We also develop customer specified laser systems.
                    • ERB15

                    • We introduces The Unique and Universal Er:YAG laser system ERB15 OEM, which is now the highest power and ultra shortest Pulses available.

                      We have been supplying our ERB15 solutions for the research, medical and industrial laser market for many years and now we use that experience to offer our unique ER:YAG Laser with 2.94 µm with less than 60 ns Puls width and 15 mJ Pulse energyat maximum repetition rate of 10 Hz.

                      The free-running Er:YAG laser designed for clinical use typically has a pulse width of a few hundred microseconds. When such a long-pulsed radiation is applied to the affected areas, the excess heat diffuses into the surrounding healthy tissues, causing damage or necrosis. Therefore, it is very important to develop a high-energy (high-peak-power) with short pulse width it means, reduce the diffusion time for the treatment of hard tissue with minimum lateral heat affecting.
