摘　　要：推导了准稳态下横向抽运的脉冲染料激光放大器的简化速率方程,提出了双侧横向抽运方式的脉冲染料激光放大器的设计原则和设计方法.应用高功率脉冲染料激光放大器的物理设计结果,研制了输出功率为50 W的脉冲染料激光放大器的实验装置.采用铜蒸气激光(CVL)作为抽运光,在此染料激光放大器上进行了实验研究,获得染料激光输出功率为52 W,抽运激光功率提取效率为41%.给出了染料激光波长、注入染料激光功率以及抽运激光的时间和空间匹配特性与染料激光放大器输出激光功率和抽运激光功率提取效率的相互关系,讨论了染料溶液浓度对双侧横向抽运方式的脉冲染料激光放大器的输出光束质量的影响.The principle and method of designing double-side transversely-pumped high-power pulsed dye laser amplifier are presented based on the simplified rate equation of transversely-pumped dye laser amplifier at quasisteady state. A double side transversely pumped dye laser amplifier with 50 W output power was developed based on the results of physical design of high power pulsed dye laser amplifier. The experimental study has been performed on this dye laser amplifier pumped by copper vapor laser （CVL）. The output power of the amplifier was over 52 W, and the extraction efficiency was up to 41%. The experimental results of the extraction efficiency and output power related to the laser wavelength, input dye laser power and pump beam＇s temporal and spatial performance have been given. Furthermore, the influence of dye solution concentration on the beam quality of the double-side transverselypumped dye laser amplifier has been discussed.
