In this research, a 1064 nm single-longitudinal-mode (SLM) vortex beam was generated from an annular-pumped Nd:YVO _4 microchip laser, in which a circular Dammann grating sex shop arles was used to reshape the 808 nm pump light into an annular intensity profile.As a result, the laser emitted read more a SLM LG _01 beam with a maximum output power of 192 mW.A straightforward technique for producing SLM vortex beams is made available by this work.
