Abstract

Recently, lasers are being used for space optical communications. However, in a space environment, space radiation is constantly incident to lasers. Therefore, the radiation tolerance analysis of lasers is an important characteristic that must be evaluated. As described in this report, we present radiation experiment results of a semiconductor laser array. This experiment measured the radiation tolerance of the laser array using a Cobalt 60 gamma radiation source. Results show that the laser array stands up to at least 100 Mrad total ionizing dose.
