一、引言 放电CO_2激光器由于有高的效率和输出等许多优点而日益强烈地吸引着人们。这方面研制工作的进展是相当快的。 最早的CO_2激光器是纵向放电,即放电方向与光轴取向一致。这种激光器的电极距离大,因此要求极高的工作电压,给实用带来许多困难和不便,于是很快出现和发展了横向放电技术,即在与光轴垂直的方向上进行放电,这就大大降低了击穿电压。但横向放电带来了
I. INTRODUCTION Discharge CO 2 lasers are attracting people increasingly strongly due to many advantages such as high efficiency and output. Progress in research and development in this area is quite rapid. The earliest CO_2 laser is longitudinal discharge, that is, discharge direction and optical axis alignment. Such a laser has a large electrode distance and thus requires a very high operating voltage, which brings many difficulties and inconveniences to practical use. Therefore, lateral discharge technology is rapidly emerging and developing, that is, discharging in a direction perpendicular to the optical axis. Greatly reduce the breakdown voltage. However, lateral discharge brought
