Abstract

Performance characteristics and reliability of the GaAs/AlGaAs one-watt laser diode are reported. The broad area gain-guided lasers have threshold current in the 400 mA range. The farfield radiation angles parallel and perpendicular to the junction are 13 deg and 25 deg, respectively. With a special-designed package which has a built-in thermo electric cooler the emission wavelength can be tuned accurately. These performances are stable during a long term operation except for 1 to 2 nm wavelength shift due to the increase of operation cur-rent in an Automatic Power Control(APC) mode. The extrapolated mean time to failure of 100-500 mW laser diodes are 20,000 hours at room temperature. A similar lifetime can be expected for the one-watt laser at operating temperatures lower than room temperature.
