The status of high-power (50-1000 mW) diode lasers for space communications is reviewed, with emphasis on monolithic devices. The current performance and future potential of single-element devices, few-element (2-3) phase-locked arrays and many-element (>10) phase-locked arrays are presented and discussed. A brief discussion of hybrid devices for achieving watt-range powers is presented as well.
