文摘

A diode-side-pumped Q-switched second-Stokes laser emitting at 1322 nm employing Nd:Gd₃Ga₅O₁₂ as the gain medium and BaWO₄ as the Raman medium was realized. With a pump power of 125 W and pulse repetition rate of 20 kHz, a maximum second-Stokes output power of 3.8 W was obtained. The corresponding diode-to-second-Stokes conversion efficiency was 3 % and the second-Stokes pulse width was 9.2 ns.
