Diode Pumped Thin Slab Solid-state Lasers

摘要

Thermal effect is a serious problem in solid-state lasers. Because of superior thermal property which owed to highaspect ratio of laser crystal, solid-state lasers with thin slab configuration can be scaling to high output power withdifferent laser crystal material and pump structure. In this paper, we present side-pumped passive Q-switched andacousto-optic Q-switched Nd: YAG lasers and end-pumped Tm: YAP lasers. We got a maximum 70W output power ofpassive Q-switched Nd: YAG laser with 220W pump power, which the pulse duration is around 1 Ons and the pulserepetition rate is higher than 10kHz. And 73W output power is got while pump power is 200W in acousto-opticQ-switched Nd: YAG lasers. Especially, we also applied the thin slab configuration to end pumped Tm: YAP laser andgot a maximum 9.6W output power which the doping concentrations is 4% and cut by c-axis.
