Abstract
Based on the beam characteristics of semiconductor lasers, a new parameter for evaluating beam quality of semiconductor lasers is introduced. The shortcomings of M2 factor used in evaluating beam quality of semiconductor lasers are discussed and its limitations are pointed out. Moreover, some important aspects of the beam quality factor are discussed. The main factors to influence collimating the beam of semiconductor lasers are analyzed. Our results give us grounds to make the following conclusions: the new propagation parameter succeeds in its universality and adaptability.
