High-energy 588nm yellow laser generation by frequency doubling of KGW Raman amplifier
A high-energy 588 nm yellow laser based on external-cavity frequency doubling of Raman amplifier was demonstrated. First, a 40 mJ pure high-performance 1177 nm first-order Stokes seed light was achieved with a KGd(WO<sub>4</sub>)<sub>2</sub> (KGW) Raman oscillator pumped by 1064 nm pulse laser. Then, a single-pass KGW Raman amplifier scheme was employed to obtain 152 mJ 1177nm Raman output. Finally, by external-cavity frequency doubling with an LBO crystal, a 74.1 mJ Raman yellow laser at 588nm with a pulse duration of 10.4 ns was obtained under the total 1064 nm pumping energy of 650 mJ. The corresponding optical to optical conversion efficiency was 11.4%.
