本文介绍了同轴脉冲氙灯泵浦的染料激光器的原理和装置.采用荧光染料若丹明6G 酒精溶液作为激活介质,得到1焦耳的激光输出,效率达0.59%.同时研究了氙灯结构和淬灭剂对激光输出效率的影响,以及染料浓度与激光波长的关系.对激光输出波形、近场分布等也作了初步的分析. In this paper, the principle and device of a dye laser driven by a coaxial xenon lamp were introduced.It was found that 1 joule laser output was achieved with fluorescent rhodamine 6G solution as an active medium, with an efficiency of 0.59% .At the same time, the structure and quenching of xenon lamp The effect of the agent on the laser output efficiency, the relationship between the dye concentration and the laser wavelength, the laser output waveform and the near field distribution are also analyzed.
