Abstract

The Lidar In-Space Technology Experiment (LITE) laser transmitter module (LTM) flight laser optical architecture has been space qualified by extensive testing at the system, subsystem, and component level. The projected system output performance has been verified using an optically and electrically similar breadboard version of the laser. Parasitic lasing was closely examined and completely suppressed after design changes were implemented and tested. Oscillator and amplifier-type heads were separately tested to 150 million shots. Critical subassemblies have undergone environmental testing to shuttle qualification levels. A superior three-color anti reflection coating was developed and tested for use on 14 surfaces after the final amplifier.
