摘　　要：A high power dual-wavelength Ti：sapphire laser system with wide turning range and high efficiency is described, which consists of two prism-dispersed resonators pumped by an a11-solid-state frequency-doubled Nd：YAG laser. Tunable dual-wavelength outputs, with one wavelength range from 750nm to 795nm and the other from 80Ohm 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 run, 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%.高力量有宽拐弯处范围和高效率的双波长的 Ti:sapphire 激光系统被描述，它由 anall 固态的加倍频率的 Nd 抽的二个分散棱柱的共鸣器组成: 钇铝柘榴石激光。与到到 850 nm 的从 800 nm 的 795 nm 和其它的从 750 nm 的一个波长范围，悦耳的双波长的产量被表明了。与在 532 nm ， 6.5 kHz 迟了的一次重复和 67.6 ns 的脉搏宽度的 23 W 的泵力量，在 785.3 mn 和 812.1 mn 的 5.6 W 的maximumdual波长产量力量与 17.2 ns 的脉搏宽度和 2 nm 的排成直线宽度，被完成了，导致 optical-to-optical 变换效率of24.4%。
