The commercial available industrial CO2 lasers are three types: transverse flow, fast Axial flow and diffusively cooled. In this paper, a new type of revolving flow CO2 laser was introduced. The research is focused on the improvement of the cavity gain distribution by developing new cavity and electrode structures. A new prototype rotational CO2 laser was developed based on this research. The laser emits TEM00 mode laser beam at 700W, and precision laser cutting experiment was conducted by this laser.
