Lasers employing unstable resonators usually produce a doughnut-shaped intensity distribution in the near-field. In this paper, we present the application of a new model in characterizing the output beams of unstable laser resonators (ULR) of different magnification (M=80, 200, and 400). As an experimental example, the output beam of Copper Vapor Laser (CVL) is characterized using this model.
