Abstract
The 1.47-1.49-μm InGaAs/InP diode laser arrays were investigated. Continuous-wave power of 25 W at 1.47-μm was obtained from a 20-element, 1-cm-wide, one-dimensional diode laser array mounted in a microchannel water-cooled heat sink. Thermal resistances of 0.56, 0.4 and 0.34 K/W were determined for arrays with fill factors of 10%, 20% and 40% respectively.
