摘要： By solving the extended Boltzmann equation and the electron number balance equation, we obtained the electron energy distribution functions (EEDFs) and the electronic excitation rates in the discharge of the radio-frequency (RF) transverse-excited intermediate pressure waveguide heliumneon laser. The population densities of the upper-laser-level Ne 3S₂ for 0.6328μm lasing and 3.39μm lasing have been determined by solving the rate euqations. The results indicate that under the proper operating conditions the population densities of Ne 3S₂ of the RF transverse-excited waveguide He-Ne laser can be increased by almost one order compared to that of a traditional longitudinal-excited capillary discharge helium-neon laser under typical working conditions. The increase of input power density and active discharge area (area scaling technique) has been proved to be reliable way to increase the output power of the RF transverse-excited waveguide atomic lasers.
