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