Currently, there are few reports of high power 1319 nm continuous lasers with high beam quality. We have demonstrated a high output power, high beam quality 1319 nm continuous-wave laser by laser diode end-pumped Nd:YAG slab with a stable-unstable hybrid resonator. With a pumping power of 477 W, an output of 96.8 W was obtained with a slope efficiency of 26.5% and stability of 0.27%. A single wavelength laser operation at 1318.7 nm was demonstrated. At an output of 91.1 W, the beam quality factors M<sup>2</sup> in stable and unstable directions were 2.95 and 1.88, respectively.展开更多

We obtained output energy of 14.6 mJ/pulse with a pulse width of 30 ns at a repetition frequency of 2 k Hz, and the corresponding peak power was 480 kW. The beam quality factors M2 in the unstable direction and the stable direction was 1.32 and 1.25, respectively.展开更多
