Abstract

A 30-mm-length YVO₄/Nd:YVO₄/YVO₄ composite crystal was used as self-Raman gain material. Yellow radiation at 587 nm was obtained by utilizing a 15-mm-length LBO as frequency-doubling crystal. The maximum average power at 587 nm is up to 8.05 W at the pulse repetition rate of 50 kHz and the pump power of 65 W, with the corresponding optical conversion efficiency of 12.38%. The shortest pulse width, the highest peak power and the maximum pulse energy were measured to be 5.57 ns, 22.1 kW, and 161 μJ, respectively.
