Kilowatt-class diode-pumped industrial lasers

TRW is developing two diode-pumped Nd:YAG laser designs (called DP1 and DP2) for high-brightness laser machining. Two DP1 lasers have been built; one has operated at its design limit of 1000 W with a stable resonator, and the other at 55 W with an unstable resonator at reduced duty cycle, in agreement with model predictions.
