In general, a great quantity of helium is applied in a high power CO2 laser. In order to reduce the operation cost of CO2 lasers, a helium-free transverse flow CO2 laser excited by high frequency has been developed. The discharge characteristics and output performance of the laser are investigated. It is shown that the maximum input power density can reach up to 21W/cm3, the laser power and conversion efficiency can reach 600W and 13% respectively for our helium free CO2 laser.
