Abstract—This work presents experimental results concerning a passively Q-switched intracavity frequency-
doubled Nd:LuVO₄/LBO green laser with a Cr⁴⁺:YAG saturable absorber operated at the wavelength of
0.53m. A maximal output power of 1.28 W was obtained at a pump power of 16.34 W, and peak power, pulse
width as well as repetition frequency were 1.48 kW, 41 ns and 21 kHz, respectively.
