横向激励高气压激光器(TEA激光器)的研制和改进是当前气体激光器件发展的重要方面之一。高气压激光器由于具有输出能量(功率)密度、效率和运转频率较高的性能;且因增益轮廓的压力加宽,能实现锁模运转获取高功率超短脉冲,以及有可能作为连续调谐的相干光源,因此受到人们的重视。在高气压下实现大体积均匀放电激励是这类器件的关键。增加工作气压和激励体积,可获取高能量输出,并充分发挥其特有的性能。但同时亦往往就导致其激活空间的不均
The development and improvement of transverse excitation high pressure laser (TEA laser) is one of the important aspects of the current development of gas laser devices. High-pressure lasers can achieve mode-locked operation for high-power ultrashort pulses due to their higher output energy (power) density, higher efficiency and higher operating frequency; and widened pressure profile due to the widening of the pressure profile, and possibly coherent tuning Light source, so by people's attention. Achieving large volume uniform discharge excitation at high pressures is key to this type of device. Increase the working pressure and excitation volume, access to high-energy output, and give full play to its unique properties. But at the same time it often leads to the unevenness of its activation space
