A single-longitudinal-mode (SLM) 2.09 μm Ho:YAG laser with anti-misalignment corner cube ring cavity was demonstrated. Unidirectional components composed of a faraday rotator and half-wave plate were used to organize the travelling wave beam propagation and to eliminate the spatial hole-burning effect. The maximum SLM power was 728 mW. The corresponding slope efficiency achieved 23.42% and the optical conversion efficiency was 7.16%. Widely tunable wavelength outputs from 2090.43 nm to 2098.37 nm have been achieved by employing a Fabry–Perot etalon. With the advantage of long cavity length and small volume, this structure of the Ho:YAG SLM laser with corner cube ring cavity is a potentially useful way to ensure narrow linewidth output and strong anti-misalignment stability.

一个2.09的单纵模式操作μ米钬激光用抗失准角立方环形腔

单纵模(SLM)2.09 μ米可儿:YAG激光用抗错位隅角立方环形腔证实。由法拉第旋转器和半波片组成的单向分量被用来组织行进的光束传播并消除空间烧孔效应。SLM的最大功率为728 mW。相应的斜率效率达到23.42%,光转换效率为7.16%。通过使用Fabry-Perot标准具,可以实现从2090.43 nm到2098.37 nm的宽可调波长输出。具有长腔长和小体积的优点,这种带有角立方环形腔的Ho:YAG SLM激光器的结构是确保窄线宽输出和强大的抗错位稳定性的潜在有用方法。
