研制了一种低温冷却的钛宝石再生环形放大器，用于产生激光等离子体光源。在10 kHz 180 W泵浦激光器的情况下，放大器输出在压缩前为40 W，压缩后为26 W。我们相信这是目前最高的平均功率输出从一个单级钛：蓝宝石放大器。热透镜的有效焦距在100 K和180 W泵浦功率下测得为2.2 m。通过在谐振器中放置1 m焦距的透镜，抑制了热透镜对谐振器模式的影响。在整个泵浦功率范围内实现了高转换效率，而无需任何额外的热补偿措施。(c)2006年美国光学学会。
A cryogenically cooled Ti:sapphire regenerative ring amplifier was developed as a laser for generating a laser-produced plasma light source. With a 10 kHz 180 W pump laser, the amplifier output is 40 W before compression and 26 W after compression. We believe it to be the current highest average-power output from a single stage Ti:sapphire amplifier. The effective focal length of the thermal lens is measured to be 2.2 m at 100 K for 180 W of pump power. With a 1 m focal length lens placed in the resonator, the effect of a thermal lens on the resonator mode is suppressed. High conversion efficiency is achieved for the whole pumping power range without any additional measures for thermal compensation. (c) 2006 Optical Society of America.
