摘要
An 880-nm laser-diode stack end-pumped cw 1342nm Nd:YVO4 slab laser with a compact positive confocal unstable-stable hybrid resonator is demonstrated. At absorbed pump power of 115 W, the output power 32.4W is obtained. The slope efficiency and optical-to-optical conversion efficiency are 42% and 28.2%, respectively. At output power of 22 W, the stable direction M2is 1.3 and the unstable direction M2 is 1.2.
