基于国产非晶态合金磁芯, 研制了采用可控硅开关、脉冲升压变压器、以及两级磁脉冲压缩网络的全固态激励电路系统, 并且应用于放电体积为29 cm3, 工作气压为100 kPa的电晕预电离小型TEA CO2激光器。讨论了提高系统能量传输效率和减小系统体积的设计方法, 并且测量了系统的工作性能以及各部分的能量损失。实验结果表明：磁脉冲压缩网络的能量传输效率大于83％, 全固态激励系统的总效率大于75％；连接激光器负载时, 输出脉冲的电压峰值约为22 kV, 电流上升时间约为100 ns；得到了脉冲能量109 mJ, 宽度70 ns的激光输出, 激光器整体效率约为3.3％。在目前的封离体积与气体循环方式限制下, 激光器最大重复频率约为100 Hz, 而激励电路部分可以达到400 Hz的工作频率。

Based on home-made amorphous cores and semiconductor switch, an all-solid-state exciter(ASSE) for pumping a corona preionized mini TEA CO2 laser has been developed, which uses silicon controlled rectifier, pulse transformer and a two-stage magnetic pulse compression system. Analysis and measurements of energy transfer efficiency are made to optimize system performance and minimize system volume. Energy transfer efficiency is over 83% for the magnetic pulse compression, and over 75% for the ASSE. Interfacing to the laser with discharge volume of 29 cm3 at 100 kPa, 22 kV discharge peak voltage and 100 ns discharge current rise time are observed. Output laser pulse with energy of 109 mJ and pulse width of 70 ns is gained. The laser is capable of operating at 100 Hz under certain volume and gas circulation condition, and the ASSE is capable of operating at 400 Hz. Therefore, long lifetime and high repetition rate operation is anticipated.
