Abstract

NASA's space-borne laser missions have been dominated by low repetition rate (<100Hz) Q-switched laser systems, which use Nd:YAG laser crystals, and are pumped by quasi-continuous wave (QCW) 808 nm laser diode arrays (LDAs). The diode group at NASA Goddard Space Flight Center (GSFC) has been responsible for the screening and qualification of LDAs for several missions. The main goal has been to identify LDAs that can withstand the harsh space environment, and minimize risks associated with LDA degradation or failure. This paper presents a summary of recent research activities, and describes the results from extended testing of multiple LDAs in air and vacuum environments.
