Laser Depth Dynamics’ (LDD) patented imaging technique is the only technology that delivers direct, geometric measurements of laser weld penetration – during the weld. Inline Coherent Imaging, or ICI, uses a low-power IR laser beam to gauge distances and the extra distance from the material surface to the bottom of the keyhole is the weld penetration. This measurement beam is directed through the same optics as the welding beam, getting focused right to the bottom of the keyhole’s vapor channel and returning the actual penetration in real time. The resulting data is equivalent to a lengthwise section of the weld, delivered instantly, with no additional labor and without destroying the part. No more destructive testing and weld quality data saved for each weld produced.
Laser Mechanisms has designed the LDD system seamlessly into all of its FiberWELD® heads and it can also be integrated into Laser Mech® CO2 beam delivery systems
Applications:
Inline coherent imaging (ICI) is the ideal process monitoring and control technology for laser welding, drilling and ablation. ICI yields unprecedented images of the interaction region in a wide variety of laser processing applications. Laser Depth Dynamics instruments are completely immune to being blinded by the process beam, plasma or other sources. LDD’s systems can deliver high-resolution, high-speed depth images of the entire process region, including the inside of the keyhole. On-line image analysis is possible, along with the ability to provide real-time feedback control of height, laser power and more.
ICI can be used with all types of lasers; Fiber and Disk, Direct Diode, CO2, Green, UV, pulsed and CW.
CW laser welding to over 10mm penetration, low power laser spot welding, surface ablation and drilling applications, as well as cladding and additive manufacturing surface measurements are all possible with ICI.

Laser beam sources are sometimes operated under full load (servicing, special operating modes), without the emitted laser radiation being utilized immediately for a processing task. In these cases > 99% of the radiation must be absorbed. Many beam sources therefore contain a PRIMES absorber.
Laser material processing systems in which the machining process does not completely absorb the laser radiation or the radiation must be “captured” (for example during a workpiece changeover) pose a similar challenge.
PRIMES absorbers are used in these instances as beam dumps. Since laser radiation is mostly not fully absorbed within laser beam diagnostics either (exception: measurement of laser beam power) various special solutions are used, which are either integrated into the diagnostics system or are needed in addition in order to guarantee the safety of people and machinery.
The PRIMES BeamMonitor (BM) is a measuring device for industrial use that performs beam diagnostics on unfocused continuous laser beams with high output power.
Since the geometric data, beam symmetry and power density distribution can all provide indications of the optical quality used, its absorption and dirt contamination level as well as alignment problems, regular checking is helpful.
The cause of the change to the optics is the often unavoidable pollution of the surfaces of the optical components or inadequate cooling. Especially in the case of transmission components such as output coupling windows or beam splitters, the dirt contamination results in higher absorption and thus creates thermal lensing. This influences beam diameter and beam divergence.
The laser beam is scanned point by point with a rotating measuring tip. The mirror mount is also moved in a linear fashion to scan the entire beam profile. In this way, a partial beam is diverted and directed at the detector in each instance.
The incoming signal is digitized and transmitted to the evaluation unit. The 14-bit A/D converter and resolution of up to 256 x 128 pixels employed enable an exact analysis even of small disturbances in the raw beam. The device was designed for use in harsh industrial manufacturing conditions and is adaptable to every spatial orientation.
The software has the following standard functions:
During the measurement, the entire beam exits the BeamMonitor again and must be absorbed as completely as possible.
Laser Mechanisms’ FiberTool™ is a patent pending device that aids in the alignment of standard multimode fibers used with Nd:YAG, Fiber and Disk lasers. Unlike thermal-based systems that have a delayed response between measurements, FiberTool produces a real-time output signal to the user that is a gauge of the alignment quality of the laser energy into the fiber optic’s core.
For a laser system to launch all of its laser energy efficiently through the fiber optic cable and maintain its beam quality, the laser energy must be focused onto only the core of the fiber optic. This focus spot must be smaller than the fiber core’s diameter and not strike the cladding layer around the core. Adjustments of the fiber launch optics in X-Y and Z are made by the laser user to get the laser beam centered on the core and at the correct focus so the optical spot is smaller than the core diameter.
Proper alignment is accomplished by having a real-time measure of the laser energy that is outside the core diameter. Laser manufacture’s feedback signals do not have the resolution necessary for proper alignment and can result in several hundred watts of wasted energy that can heat the external focus head – potentially causing damage to these optics.
FiberTool provides the only true, real-time measure of the laser energy outside the fiber core and allows the laser operator to adjust the fiber launch system while monitoring this signal until a minimum reading is attained. Any time a fiber is removed and replaced, or a new fiber is connected to the laser source, FiberTool should be used to ensure proper fiber alignment and the condition of the laser launch system.
The PRIMES BeamControlSystem (BCS) enables the automatic measurement of the most important laser beam parameters within industrial laser processing lines. Beam power, as well as focal measurements and power density distributions are measured by the system which is shielded, rendering it completely dust-proof.
Features:
The PRIMES FocusMonitor is a mechanically scanning diagnostic system for analyzing continuous laser beams – even at high laser beam power. These laser beam sources are used in laser material processing for laser beam welding, cutting and surface processing.
The geometrical dimensions of the focused laser beam are determined, as well as the focal position in space, the beam parameter product and the diffraction index.
Where the limitations concerning the measurement window sizes and the maximum power densities are adhered to, CO2 laser systems up to 50 kW and solid-state laser systems up to 30 kW optical power can be measured.
The laser beam is scanned within a 3D measuring column with a special measuring tip. There is a small drill hole in the measuring tip (typical diameter: 20 μm), through which a small portion of the laser beam enters. This beam portion is directed by means of two deflecting mirrors at a detector, which is selected and configured depending on laser power and wavelength.
The electronics transmit the digital signal for evaluation via the PRIMES LaserDiagnosticsSoftware to a PC. This 3D analysis is requisite for the comprehensive representation of a caustic near the focal point.
For different wavelengths, pyro-electric detectors or photo diodes are used. The divergence of the focused laser beam of CO2 lasers is quite low. The ratio of the focal distance of the focussing optics used to the beam diameter of the unfocused beam is normally higher than 5, i.e. the effective f-number would be 5.
Solid state lasers, such as diode, disk or fiber lasers, on the other hand, are focused with smaller f-numbers.
Tailored measuring tips are available for the various divergences and wavelengths.
For this reason, different laser beam sources and systems can only be measured by the correct selection of the measuring tip and the associated detector at maximum laser beam power.
The high speed of the rotating measuring tip allows the analysis of high power densities. Thanks to the high dynamic range of the analog-digital converter used, a very good signal-noise ratio is achieved.
Very low intensities are precisely imaged, as are high peak intensities. This is one of the prerequisites for automatic measuring of caustics in the area near the focal point over at least four Rayleigh lengths, according to ISO 11146. This means that over this measuring range along the laser beam axis, the power density varies by at least a factor of 4. However the signal-noise ratio must be > 40. Detectors with dynamic ranges > 85 dB support this requirement.
Warning: During the diagnosis, almost no laser beam power is absorbed. More than 99% of the laser beam power must be collected and absorbed after passing through the FocusMonitor. This can be achieved with a PRIMES PM48 or PM100 PowerMonitor.
