摘　　要：为了实现He-Ne激光器的远距离点亮,从He-Ne激光器的电特性及电源负载特性入手,通过FFT变换分析,解释了冲击电压钝化的原因,并通过建立高压线分布参数模型,导出了电压衰减常数,从理论上提出使用屏蔽传输线并建立一个匹配网络,通过实验加以验证,成功解决了冲击高电压远距离传输的问题,从而实现了He-Ne激光器的远距离点亮,具有重要的工程应用价值。For implementation of lighting He - Ne laser at long- distance, the electric characteristics of He - Ne laser and power load are analyzed. Through analysis to FFT transform, the reason for impulse voltage inactivation was found. And attenuation constant was obtained by building a model for distributed parameters of high voltage line. It＇ s suggested theoretically that shielded transmission line is used to take the place of normal line for building up a matching network. The accuracy of this method has been proved by experiments. The problem of long - distance transmission of high impulse voltage has been solved. Thus lighting He - Ne laser at long - distance has also been realized. The result is of great importance to engineering application.
