We developed an octave-band tunable optical vortex laser based on a 532 nm optical vortex pumped optical parametric oscillator with a simple linear-cavity configuration by employing cascaded non-critical phase-matching LiBO crystals. The optical vortex output was tunable from 735 to 1903 nm. For a pump energy of 9 mJ, an optical vortex pulse energy of 0.24-2.36 mJ was obtained, corresponding to an optical-optical efficiency of 0.3-26%.
我们基于一个532纳米的光学涡旋泵浦光学参量振荡器，通过采用级联非临界相位匹配的LiBO晶体，开发了一种具有简单线性腔配置的倍频程可调谐光学涡旋激光器。该光学涡旋输出在735至1903纳米范围内可调谐。对于9毫焦的泵浦能量，获得了0.24 - 2.36毫焦的光学涡旋脉冲能量，对应的光光效率为0.3 - 26%。
