Beijing Institute of Technology, Beijing 100081,ChinaIn order to get the high output power, a RF excited diffusively cooled all-metal slab waveguide CO2 laser was reported, in which gas discharge region was constructed by two aluminum side walls and aluminum electrodes. The region dimension was 2 mm height×20 mm width×386 mm length, and the gas composition was CO2:N2:He:Xe=1:1:3:0.26. This technique replaced the old ceramic and metal sandwich waveguide technique.The optimum out power 127 W was achieved from the RF excited diffusively cooled all-metal slab waveguide CO2 laser with the longitudinal voltage uniformity distribution technique and scaling area technique. The electro-optic conversion efficiency was about 14%.
