Abstract
A positive-branch unstable resonator with a step reflectivity mirror used in high power CO2 laser is presented.This resonator is investigated both theoretically and experimentally.The output power of this resonator is 700 watts.W.ith on efficiency of 7.9 percent.The divergent angle of far-field is 2.1 mrad.
