Abstract

Lasers for some space applications have operational requirements for lifetime, efficiency and power output which can only be met by development of all solid-state laser sys-tems. Laser diode pumping of neodymium host materials has demonstrated good efficiency and lifetime at low power levels. This paper addresses the issues involved in scaling to the kilowatt power level. A design configuration for stand-off coupling of rack and stack laser diode arrays to a laser slab is presented which satisfies all of the above criteria. Design examples for near term efficiencies of >5% and long term efficiencies >15% for both cw and pulsed type lasers in the one kilowatt range are used as illustrations of the technique.
