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 $189\mathrm{W}$ and an average Q-switched output of $169\mathrm{W}$ at $10\mathrm{kHz}$ with an $M^2$ 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 $93\mathrm{W}$ green light at $10\mathrm{kHz}$ with a pulse width of $10.7\mathrm{ns}$ . The efficiency of second-harmonic generation was up to 57%.
