Highly-reliable CW operation of 100 mW GaAlAs buried twin ridge substrate lasers with nonabsorbing mirrors

Long-life GaAlAs lasers with 100-mW fundamental-transverse-mode operation are discussed. This excellent degree of operation has been attained by using nonabsorbing mirrors for suppression of mirror degradation and a twin-ridge substrate structure for stabilization of the transverse mode. It has been found that under 100 mW CW operation at 50 degrees C, degradation is insignificant even after 6000 h.<
