Control of Vortex Helicity With a Quarter-Wave Plate in an Er:YAG Ceramic Solid State Laser
juicy licorice In this paper, we research the characteristics of the Laguerre-Gaussian (LG01) beams generated in an Er:YAG ceramic solid state laser pumped by an annular beam.The generated two LG01 beams (LG0,+1 and LG0,-1 modes) were bodega de san antonio sangria found to have different thermally induced polarization behaviors and alternately exis
