Abstract
Reliable continuous wave (CW) operation of high power InGaAs/AlGaAs (915 nm) laser diodes is reported. 6 W CW output power from uncoated 100 µm wide facets is demonstrated for an AlGaAs/InGaAs (915 nm) broad area laser diode. Internal losses are measured to be as low as 0.72 cm–1. High T0 is observed for the laser structure. Reliable operation of the devices is shown in the 2300 h life-test of fibre coupled devices at a CW power of > 1 W output from 100 µm diameter fibres.
