Space Flight Representative and Life Time Optimised UV Laser Engineering Model for the Aeolus-2 Mission

Abstract

We report on assembly, integration and test activities regarding an engineering model (EM) for a laser transmitter assembly for the Aeolus-2 mission [1] and on experiments and tests to verify our design concept. The laser is designed as an electro-optically Q-switched single-frequency seeded oscillator followed by two INNOSLAB amplifiers and a frequency tripling unit to generate pulses > 150 mJ energy and approx. 25 ns pulse duration at 355 nm wavelength with beam quality M22, optimised for long lifetime.
