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 and an average Q-switched output of at with an 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 green light at with a pulse width of . The efficiency of second-harmonic generation was up to 57%.
