A high power dual-wavelength Ti:sapphire laser system with wide tuing range and high efficiency is described, which consists of two prism-dispersed resonators pumped by an all-solid-state frequency-doubled Nd:YAG laser.Tunable dual-wavelength outputs, with one wavelength range from 750 nm to 795 nm and the other from 800nm to 850nm, have been demonstrated. With a pump power of 23 W at 532nm, a repetition rate of 6.5kHz and a pulse width of 67.6ns, the maximum dual-wavelength output power of 5.6 W at 785.3nm and 812.1 nm, with a pulse width of 17.2ns and a line width of 2nm, has been achieved, leading to an optical-to-optical conversion efficiency of 24.4%.
