Objective:To study the effects of injection locked unstable cavity on beam quality in Copper Vapor Laser.Methods:injection locked unstable cavity on beam quality in Copper Vapor Laser.Results:The beam diˉvergence was dramatically reduced to0.15mrad.The saturation injection power is given qualitatively in this paper.Conclusion:It indicates that for large gain Copper Vapor Laser,the injection-locked amplification is an optimal approach,it can depress multi-longitudinal and higher transverse mode in high gain medium,thus leads to higher efficiency and beam direction in Copper Vapor Laser.
