About us

BeamXpert GmbH was founded in 2017 as a spin-off of the Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, in Berlin-Adlershof. The company's expertise lies in the areas of laser beam characterization and numerical calculation of laser beam propagation through optical systems.

As their first product BeamXpert®DESIGNER is on the market since 2018. The software calculates the propagation of laser radiation through optical systems in real time and is exactly adapted to the everyday needs of laser developers and laser users.

BeamXpert®DESIGNER can be learned quickly, offers a CAD-like 3D representation, allows interactive moving and aligning of elements with the mouse and contains an optical component database. It can predict the beam propagation parameters defined in ISO 11146 and enables the quantitative determination of the influence of aberrations on the beam quality. All this allows precise results to be achieved quickly and significantly accelerates the workflow.

Products and services

BeamXpert®DESIGNER – Real-time simulation of laser radiation in optical systems.

BeamXpert®DESIGNER provides parameters such as beam diameter, waist position and Rayleigh length as well as additional beam propagation parameters in accordance with ISO 11145 and 11146 at any plane in the optical setup.

BeamXpert®DESIGNER uses two different modeling approaches. The first model applies the propagation of the second order moments of the radiation field. A proprietary approach allows a less restrictive application of the paraxial approximation. Since the calculation is very fast, the simulation can be performed in real time. In the second model, the laser radiation is represented by a bundle of geometrical-optical rays propagated through the system using classical raytracing. The effect of aberrations (e.g. due to inappropriate lens selection or arrangement) can be detected by analyzing the beam quality factor of the beam as it passes through the optical system.

1. Use Case - Collimation of Diode Laser Radiation

In order to apply the high beam quality of diode lasers, the highly divergent radiation has to be formed to a parallel laser beam first. This collimation is typically done by one or more microlenses. Using improper lenses can significantly deteriorate the beam quality supplied by the laser diode.
With the help of BeamXpert®DESIGNER, the lenses best suited for this use can be determined. In addition, the effect of possible lens misalignments on the beam quality can be quantitatively determined.

2. Use Case - 6 kW Fiber Coupled Diode Laser Pump Module

The beams of 56 diode lasers, arranged on two stacks, are collimated separately, optically combined to a total beam and coupled into a single fiber. The optical system was developed with BeamXpert®DESIGNER. Despite the large number of radiation sources, fluid working in real time was still possible. With the ray model it was possible to correctly determine the coupling losses.

3. Use Case - Frequency Conversion

In certain wavelength ranges, laser radiation cannot be generated directly. Instead, laser radiation is converted into the desired wavelength range using nonlinear crystals. In order to achieve optimum conversion efficiencies, the laser radiation must be focused into the crystal with closely defined parameters (focus diameter and position, Rayleigh length, etc.).
With BeamXpert®DESIGNER it is possible to determine the necessary lens combinations quickly and reliably.
