Abstract

We demonstrated a laser-diode pumped Nd-doped yttrium gallium garnet crystal laser at 1110 nm for the first time to our knowledge. By suppressing the oscillation at about 1.06 μm, continuous-wave output power of 2.1 W at 1110 nm was achieved. With a Cr:YAG as the saturable absorber, the passive Q-switching performance at this wavelength was obtained. The shortest pulse width and largest pulse energy were 31.5 ns and 22.7 μJ, respectively. Laser radiation at this wavelength is an important source for detecting carbon monoxide poisoning by simple frequency doubling with a nonlinear crystal.

摘要

我们首次展示了一种激光二极管泵浦掺钕钇镓石榴石晶体激光器，波长为 1110nm。通过抑制约 1.06μm 的振荡，我们获得了 2.1W 的连续波 1110nm 输出功率。采用 Cr:YAG 作为可饱和吸收体，获得了该波长的被动调 Q 性能。最短脉冲宽度和最大脉冲能量分别为 31.5ns 和 22.7μJ。该波长的激光辐射是通过非线性晶体简单倍频检测一氧化碳中毒的重要光源。
