摘要：
10.9W continuous wave (CW) optical power is achieved from a 100μm aperture InGaAs/AlGaAs (915nm) 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 2mm long laser diode. Reliability studies on 40μm aperture laser diodes have been carried out for over 10kh at approx. 24mW/μm for a total output power of 950mW under CW condition. Under these conditions, the extrapolated lifetime of the diodes is 56kh.
