Degradation analysis of individual emitters in 808nm QCW laser diode array for space applications

摘要

Degradation analysis of 808nm QCW laser diode array for space application has been investigated by using individual emitter characterization technique. We found that homogeneity of electro-optical characteristics at emitter level along the bar is a relevant parameter to ensure the reliability of the bars. This work is focused on the importance of individual emitter characterization and aging test results analysis up to 4.47 Gshots.
