【Abstract】 A high efficient laser diode end pumped Nd∶YAG CW laser is presented in the paper.A quasi continuous wave 1W laser diode is used as pumping source and a φ 5mm×5mm Nd∶YAG rod is used as laser medium.Its resonant cavity is a plane concave cavity and output mirror is a concave mirror.We have investigated the effects of the output mirror with different reflectivities and curvature radii on output power.We have obtained that the optimal reflectivity is 98.3%,optimal curvature radius is 155.6mm,maximal output power is 244.4mW,optical optical efficiency is 42.1%,slope efficiency is 62% and cavity length is 37.4mm.更多还原
