Abstract
In this paper, Xe and He-Ne atomic lasers and CO2 molecular lasers excited by 30 MHz approximately 2 GHz frequency have been studied, and then put forward the key of getting high efficiency is how to control the electron energy of discharge space. In the mobility-dominated discharge space of Xe laser, the product of gas pressure and input power is constant. In He-Ne laser, the product of gas pressure and power supply frequency is a constant in plasma discharge space of the glass tube under the optimum laser output. As to the slab waveguide CO2 laser, the center of discharge space is quasi-Faraday dark region. But to the high power CO2 laser (flow gas) the discharge space is plasma. Since there demand much lower electron energy, and high density for CO2 laser, only in discharge structure there are several designing schemes can be referenced.
