一、概述高重复频率的晶体(YAG·红宝石或钕玻璃等)、脉冲氙灯成聚光腔若不冷却,工作温度越高,输出能量和效率越低(因温度升高,使谱线加宽,量子效率降低),所以,只有和冷却系统配合,才能正常工作。目前,国内所用冷却液主要是水,多数是用蒸馏水。有的还在水中加入少量的重铬酸钾或亚硝酸钠,也有的加入少量的高锰酸钾,以滤 First, an overview of high repetition rate crystal (YAG · ruby ​​or neodymium glass, etc.), pulsed xenon lamp into the condenser cavity if not cooled, the higher the operating temperature, the lower the output energy and efficiency (due to temperature increases broaden the spectrum , Lower quantum efficiency), so only with the cooling system to work properly. At present, the coolant used in China is mostly water, mostly distilled water. Some still add a small amount of potassium dichromate or sodium nitrite in the water, and some add a small amount of potassium permanganate to filter
