CW optical output power was investigated in (Al-Ga)As double heterostructure lasers. An analysis on CW optical power is presented, and parameters related to device characteristics and heat-sinking are analyzed in order to obtain laser operation with high CW optical power. 20-30 mW CW optical power was obtained routinely from each mirror of' lasers with a 15 μm wide stripe and a 250 μm long cavity at a typical operating current of 200 mA. Lasers with a Si heat sink can deliver comparably high CW optical power under proper choice of design parameters. Several lasers delivered 85 mW in CW with a Si heat sink from each mirror at 310 mA, before the catastrophic optical mirror damage occurred. Conditions for long life operation are also discussed.
