Abstract
10.9 W continuous wave (CW) optical power is achieved from a 100 μm aperture InGaAs/AlGaAs (915 nm) laser diode. No catastrophic optical mirror damage was observed. Diodes also demonstrated strong resistance to thermal damage. Power conversion efficiency as high as 59% has been measured for a 2 mm long laser diode. Reliability studies on 40 μm aperture laser diodes have been carried out for over 10 kh at ~24 mW/μm for a total output power of 950 mW under CW condition. Under these conditions, the extrapolated lifetime of the diodes is 56 kh
