Effects of RF Preionization in a Transverse-Discharge-Excited cw CO Laser
An RF preionization has been applied to a closed-cycle subsonic transverse-discharge-excited CW CO laser. Its fundamental characteristics are described in this paper, where an emphasis is placed upon the discharge behavior. By applying the RF preionization. an input power density of 8.7 W/cm3 is obtained at a gas temperature of 202 K under a relatively low reduced electric field (E/N).
