Abstract: A simple scheme is proposed for efficient frequency doubling in a Nd:YAG laser transversely pumped by diode lasers. The average output TEM₀₀-mode power of the 1064-nm Q-switched laser at the Q-switching rate exceeding 20 kHz is 15 W. The radiation power at the second harmonic frequency (λ = 532 nm) is found to be 12 and 8.3 W for KTP and LBO crystals for Q-switching rates f≥20 kHz and 10 kHz, respectively. The maximum second-harmonic conversion efficiency is ~80%.
