2026-01-06 Single-longitudinal-mode vortex Nd:YVO4 laser using a circular Dammann grating for pump shaping doi:10.57760/sciencedb.34923 en 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.
