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(WO4)2 (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%.
A high-power and widely tunable Ti: sapphire laser dual-end pumped by a 10 kHz 532 nm pulsed laser with an output wavelength of 720–890 nm was demonstrated. An effective thermal management was achieved by a dual-end pumping scheme and an elaborate symmetrical flat cavity design, which greatly improved the upper limit of pump power. When the pump power was 41.5 W, a maximum output power of 10.36 W at 800 nm was obtained with a linewidth of 2 nm and a pulse duration of 17 ns. The corresponding conversion efficiency was 25 %.
