摘要

这项研究利用环形泵浦 Nd:YVO4 微芯片激光器产生了 1064 nm 单纵模（SLM）涡旋光束，其中使用了环形达曼光栅将 808 nm 泵浦光重塑为环形强度曲线。因此，该激光器发出的 SLM LG01 光束的最大输出功率为 192 mW。这项工作提供了产生 SLM 涡旋光束的直接技术。

Single-longitudinal-mode vortex Nd:YVO4 laser using a circular Dammann grating for pump shaping

In this research, a 1064 nm single-longitudinal-mode (SLM) vortex beam was generated from an annular-pumped Nd:YVO₄ microchip laser, in which a circular Dammann grating was used to reshape the 808 nm pump light into an annular intensity profile. As a result, the laser emitted a SLM LG₀₁ beam with a maximum output power of 192 mW. A straightforward technique for producing SLM vortex beams is made available by this work.
