摘要：

A simple and highly reliable package consisting of a 1-cm-long AlGaAs laser diode array mounted directly on a silicon microchannel cooler has been demonstrated. 3.4×109 shots were logged on this device at an average optical output of 8.75 W with only a 6% increase in current required to hold the light output constant. This extrapolates to a current doubling lifetime of 1.6×1011 shots. The thermal impedance was also measured to be 0.014 °C/(W/cm2).
