A practical high-power CO2 laser welding and cutting equipment with high beam quality was introduced,the optical system was analyzed.The three-folded resonator and small aperture are adopted in the equipment,the output of laser power is 3kW,the instability is less than ±4%,the divergence of beam is 1.6mrad,the modes are TEM00 and TEM01.The application of three-workspace light switched system improves the efficiency.The equipment can be used not only in welding with lens focusing,but also in cutting with off...
