Abstract

Efficient, high-power operation of a diode-bar-pumped Nd:YAG laser on the quasi-three-level transition at 946 nm is reported. Longitudinal pumping of a simple folded cavity by a 20-W diode bar, with a two-mirror beam shaper used to reformat 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 33%.

摘要

报道了一种二极管条泵浦的Nd:YAG激光器在946nm准三能级跃迁上的高效、高功率运行情况。用一个20W的二极管条纵向泵浦一个简单的折叠腔，使用双镜光束整形器对二极管条的输出进行重新整形，在室温下，对于13.6W的入射泵浦功率，在1.5倍衍射极限光束中产生了约3W的连续波输出功率。相应的光斜率效率约为33%。
