Abstract

We reported on an all-solid-state double Nd:YAG slab laser. The laser was based on two diode end-pumped Nd:YAG slabs and a stable–unstable hybrid resonator. A cw output of 189W and an average Q-switched output of 169W at 10kHz with an M2 factor of 1.5 in the slow direction and 1.7 in the fast direction were obtained. We demonstrated efficient near-field frequency doubling by imaging the one-dimensional top-hat near-field to a lithium triborate frequency doubler. We obtained 93W green light at 10kHz with a pulse width of 10.7ns. The efficiency of second-harmonic generation was up to 57%.
