Simple high efficiency diode-pumped Nd:YVO_4 slab laser

摘要

A diode laser-pumped Nd: YVO_4 slab laser with side pumping configuration is presented in this paper. A folded confocal resonator configuration produces a maximum of 7mJ multi mode laser energy for the output coupler reflectivity of 70 percent. The optical-to-optical conversion efficiency of 29.86 percent. and slope efficiency of 35.6 percent are reported in this investigation. Straight-through resonator arrangement and directly side-coupled technique provide high efficiency with design simplicity of this laser.
