摘要：

A simple approximation is developed for solving the ''whispering gallery modes'' of a microdisk laser structure using conformal transformation and the WKB approximation. Using this method the spontaneous emission coupling factor of microdisk lasers is estimated. The result predicts a beta value of the order of 10(-1).
