Room-temperature diode-bar-pumped Nd:YAG laser at 946nm

By W.A. Clarkson, R. Koch and D.C. Hanna

Abstract

Efficient, high-power operation of a diode-bar-pumped Nd:YAG laser on the quasi-three-level transition at 946nm is reported. Longitudinal pumping of a simple folded-cavity by a 20 W diode bar, using a two-mirror beam-shaper to re-format the bar's output, yields a continuous-wave output power at room temperature of ~3 W in a 1.5 times diffraction-limited beam for 13.6 W of incident pump power. The corresponding optical slope efficiency was approximately 32%
