Space debris detection and the use of laser effectors with beam propagation over long distances through the atmosphere in the areas of security and defence require a cross-technology combination of laser tracking and imaging methods. At the Institute of Technical Physics, imaging and tracking systems are tested under real conditions for the respective requirements of beam propagation. The Active Optical Systems department develops systems that enable compensation for atmospheric distortion when transmitting laser radiation and for imaging objects using active laser illumination.
The Institute of Technical Physics also has expertise in the qualification of optical components such as laser optics and frequency conversion crystals for their use at high power and under space conditions. To this end, the optics are subjected to standardised damage threshold tests. Non-linear optical crystals are compared for their conversion efficiency and resistance to radiation under proton and gamma radiation. In addition, research is being carried out into laser-induced contamination.
