Abstract
We report our findings on laserdiode endpumped YbYAG 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 09 An opticaltooptical efficiency of 229 and slope efficiency of 371 were obtained and the beam quality M 2 factors in the unstable and stable direction were 104 and 101 respectively
