Abstract

The Franco-German »MERLIN Project« was initiated in 2010. The small satellite MERLIN (Methane Remote Sensing LiDAR Mission) will map the methane in the earth’s atmosphere. Fraunhofer ILT has developed the LiDAR laser source and is currently integrating the Engineering Qualification Model. The laser consists of a laser oscillator pumped by fiber coupled diode laser modules, an INNOSLAB amplifier and KTP-based frequency converter. The amplifier pump is based on qcw stacks which are homogenized in the slow axis direction and focused in the fast axis direction. We will present the design of the pump optics and results of reliability tests. In addition, we will give an outlook on the development of a laser source for a future wind LiDAR mission.
