Abstract

To utilize effectively large-scale monolithic 2-D arrays of diode lasers for high average output power, microchannel heat sinks and microlens arrays are needed. The heat sinks are required to dissipate heat loads of several hundred W/cm², while the microlenses permit collection and concentration of the array output for optical pumping of solidstate lasers and improve the till factor (and hence the beam pattern) in coherent operation of arrays.
