Radiation tests

The LEMON consortium has conducted the radiation tests for the most critical devices used within the lidar system. For the non-linear Optical Parametric Oscillator (OPO) crystals and the highly non-linear fibers the post radiation tests have been conducted, too. The results of those have proven that the materials used for the airborne demonstrator are also suitable for a later implementation in a space lidar system. The tests on the laser crystals of the Frequency Reference Unit (FRUit) comb generator and Silicon Nitride (SiN) integrated photonic circuits are pending and expected within the next two months.
