title: Intracavity sum-frequency diode side-pumped all-solid-state generation yellow laser at 589 nm with an output power of 20.5 W.
abstract: A laser diode side-pumped all-solid-state pulse laser at 589 nm with high power, high conversion efficiency, and a small volume is demonstrated by intracavity sum-frequency generation. By carefully optimizing the cavity and adopting various techniques, a quasi-cw free oscillation yellow laser source, which has a maximum output power of 20.5 W, a repetition rate of 14.49 KHz, and a pulse width of 157 ns, is developed. The optical-to-optical conversion efficiency is up to 5.11%, and the power stability is better than 2% in 2 h.
