研制了适用于激光器的电感储能发生器(GIES),并研究了它在高压混合气体中的放电和激光参数。研究表明,电感储能发生器可产生高压预脉冲并引起放电电流的突然增大,可在不同的混合气体中形成长时间的稳定放电,从而方便地控制和优化每一种气体混合物的预脉冲参数。在未知IES击穿电压和首次放电幅度下的参数时,电流尖峰会按因子1.5~2减少,从而产生纯激光参数。得到了氮气激光器的最大的辐射功率,输出能量和脉冲持续时间,在脉冲持续时间为40 ns时,紫外输出高达50 mJ,红外输出高于25 mJ,实现了氮分子激光跃迁的级联激射。因此C3Пu-B3Пg带总的脉冲持续时间延长至100 ns。在XeCl,XeF和KrF受激准分子激光器中,脉冲宽度和输出能量都得到了改善。XeF激光器的最大效率达到了1.6%,同时峰值输出能量达到了0.85 J,最大脉冲持续时间超过了200 ns。在248 nm波长处,效率3.3%的KrF激光器产生的160 ns脉冲能量高达650 mJ,最终得到了效率为7.7%~10%的非链式HF(DF)激光器。演示了基于CO2分子高峰值功率的有效运行,结果表明,激光器在10 600 nm处的输出能量为6.2 J,转换效率高达25%。
Inductive energy storage generator (GIES) is developed for laser and its discharge and laser parameters in high pressure gas mixture are studied. Studies have shown that inductive energy storage generators can generate high-voltage pre-pulses and cause a sudden increase in discharge current, resulting in long-term stable discharges in different mixtures, allowing for easy control and optimization of the prepulse for each gas mixture parameter. At unknown IES breakdown voltage and first discharge amplitude parameters, the current spikes are reduced by a factor of 1.5 to 2, resulting in pure laser parameters. The maximum radiant power, output energy and pulse duration of the nitrogen laser were obtained. The UV output was up to 50 mJ and the infrared output was higher than 25 mJ at a pulse duration of 40 ns. The cascade lasing of nitrogen molecular laser was realized . Therefore, the total pulse duration of the C3Пu-B3Пg strip is extended to 100 ns. In XeCl, XeF and KrF excimer lasers, the pulse width and output power are improved. The XeF laser achieves a maximum efficiency of 1.6% with a peak output energy of 0.85 J and a maximum pulse duration of more than 200 ns. At 248 nm, a KrF laser with 3.3% efficiency produces 160 ns of pulse energy up to 650 mJ, resulting in a non-chained HF (DF) laser with an efficiency of 7.7% -10%. Demonstrating the efficient operation based on the high peak power of CO2 molecules, the results show that the laser has an output energy of 6.2 J at 10 600 nm and a conversion efficiency of up to 25%.
