Abstract
A compact, high power and high beam quality laser diode stacks partially end-pumped quasi-continuous wave slab laser with hybrid resonator is demonstrated. Using this configuration, with Nd:YVO4 as the slab gain media, 101 W output power is obtained when the pumping power is 216.5W with the repetition of 1kHz, the optical-to-optical efficiency and slope efficiency are 46.7% and 51.14%, respectively. The beam quality M2 factors in the unstable direction and the stable direction are 1.36 and 1.56 respectively at the output power of 101 W.
