Abstract

We report our findings on laser-diode end-pumped Yb:YAG slab output characteristics when using a compact positive confocal unstable–stable hybrid resonator at room temperature. Preliminary experimental results show that for an absorbed pump power of 680 W, a maximum output power of 156 W was produced at 1030 nm with a stability of 0.9%. An optical-to-optical efficiency of 22.9% and slope efficiency of 37.1% were obtained, and the beam quality M² factors in the unstable and stable direction were 1.04 and 1.01, respectively.
