Laser Modules Lab

We develop customized miniaturized laser modules for numerous fields of application.
With highest precision we integrate diode lasers of high spectral radiance as well as optics for beam shaping, external resonators, electronics and frequency doubling crystals. On this basis, oscillator-amplifier combinations, fiber-coupled modules, modules with coherent beam combination and integrated pulse excitation with small size are also feasible.
Our high-power laser modules reliably emit light in the NIR range up to 30 watts of continuous wave optical output power and 1 to 3 watts in the visible spectral range (red, yellow, green and blue).
From these we develop, for example, light sources for STED and fluorescence spectroscopy.
In our laboratories, laser sources in the UV-range and hybrid integrated miniaturized quantum light modules are created, which are based on entangled photon pairs and make the mid-IR spectral range accessible.
In addition, we are developing pulse sources with integrated electronics (laser drivers) that make it possible to generate very precise and ultra-short current pulses up to 6 amps with pulse widths in the ps range. These optical pulses reach an output power of more than 3 watts.
