【Abstract】 Through the ABCD method for light transformation,the radius of curvature of the outer surface of output mirror of a laser resonator is an important factor in influencing the beam property.In some practical applications, for example laser machining for large wok piece,we can desigh a proper radius of the curvature of the output mirror to improve the beam quality to be suitable for the application requirement .更多还原
