Self-frequency doubling of a laser diode array pumped Q-switched NYAB laser

Experimental results of a Q-switched NYAB self-frequency-doubled laser end-pumped by a laser diode array (LDA) are reported. A cw 0.5-W LDA was used as an end-pumping source. An average output power of 6 mW and repetition rates of 16 kHz at 0.53 μm were achieved. The pulse durations at 1.06 and 0.53 μm were 45 and 25 ns, respectively, and a peak output power at 0.53 μm of 20 W was achieved at the Q-switching repetition rate of 100 Hz.
