Reliability of 680-nm window laser diodes at 50-100 mW CW operation

摘要

By reduction of the operating current density due to a long cavity length of 900 /spl mu/m, reliable 5,000-hour operation of 680-nm window lasers has been realized under the conditions of 70 mW at 60/spl deg/C and 100 mW at 40/spl deg/C for the first time.
