Photodigm Inc.Laser diodes have been used for many years in space applications. Their main use has been as pumps for solid-state lasers, and qualification methodologies have been developed for these applications. In recent years, however, increasingly complex scientific payloads have required precision lasers for metrology, calibration, and environmental sensing. As a result, payload engineers have developed increasingly stringent screening criteria for space qualification to ensure the reliability and performance of precision laser diodes for space applications. Through deliveries with its existing space customers, Photodigm has developed detailed certification procedures to certify its precision DBR lasers, third party Commercial Off-The-Shelf (COTS) lasers, or other components on a lot-specific basis for use in space missions.
