Efficient laser operation at wavelengths around 1.6 μm is demonstrated in Er (1.1 at. %):YVO₄. The crystal is in-band pumped at 1536 nm by a fiber laser, resulting in a maximum slope efficiency of 57.9% with respect to the absorbed pump power and 2.3 W of maximum output power. Wavelength tuning with a birefringent filter to wavelength bands suitable for CO₂ lidar applications at 1579 and 1603 nm could be obtained.
在掺铒 1.1 原子%的 YVO₄ 晶体中实现了在 1.6 μm 左右波长的高效激光运转。晶体通过光纤激光器在 1536nm 波段进行带内泵浦，相对于吸收的泵浦功率，最大斜率效率为 57.9%，最大输出功率为 2.3W。通过双折射滤波器可以调谐波长到适合 CO₂ 激光雷达应用的波长带，分别为 1579nm 和 1603nm。
