The quality assurance method of semiconductor pump laser for space application

Based on the situation that imported low quality level of the semiconductor pump lasers are selected for most China space applications ,via analyzing the basic characters and failure mechanisms, and researching on relative international standards, this paper provides a quality assurance test items and procedures that applies to the imported low quality level semiconductor pump lasers, and introduces techniques and conditions for each tests. It is proved by an actual case that the quality assurance methods this paper provided are effective and feasible, and can be adopted by all the quality assurance for the imported low quality level pump lasers for China space application in the future.
