Characteristics of HF-excited CO2 laser with new pumping system

A large capacitive coupling discharge main pumping system and a high frequency excited transverse CO2 laser have been studied. By means of special high dielectric constant ceramic covered electrodes as main electrodes and preionization electrodes, the discharge characteristics and output characteristics of CO2 laser are presented. In our pumping system, the high input power density, stable discharge and output power density, stable discharge and output power have been achieved. In the compound dielectric electrodes with preionization pumping system, the discharge is more homogeneous and stable.
