Abstract

High frequency excitation is increasingly substituting for dc discharge excitation of the high power CO₂ laser, in general, a great quantity of helium is applied in a common high power CO₂ laser. In order to reduce the operation cost of CO₂ laser, a helium-free transverse flow CO₂ laser excited by high frequency has been researched. In this paper, some of the investigations of discharge characteristic and output characteristic are presented. It is shown that, under our experimental condition substituting Ar for He in the CO₂ laser, the maximum input discharge power density is stable up to about 21 W/cm³, the output laser power and photoelectric efficiency are 600 W and 13%.
