High brightness semiconductor lasers are potential transmitters for future space lidar systems. In the framework of the European Project BRITESPACE, we propose an all semiconductor laser source for an Integrated Path Differential Absorption lidar system for column-averaged measurements of atmospheric CO2 in future satellite missions.

The purpose of this paper is to analyse the effects of proton displacement damages up to 8•1011p/cm2 and total ionisation dose up to 100Krad (Si)) at room and low temperature (i.e. 25ºC and -40ºC) on custom assemblies of High Voltage (HV) Optocouplers. The HV opto-coupler assembly, radiation setups for low temperature Gamma and Displacement Damage radiation tests are described in detailed.
