Characteristics of Thermal Lens in a Copper-Vapor Laser,

Abstract

The thermal lenses in operating copper vapor lasers and in the fused silica windows were measured by using of the deflection method and the interferometer method respectively. Experimental results show that the overall thermal lens is composed of a negative lens in the discharge gas and two positive lenses in two pieces of laser windows. Theoretical analysis agrees well with experimental results.
