Abstract: The radiuses of equivalent Gaussian beam of different kinds of lasers are studied by using 86.5% loop enclosing power method.Combining with the experiments of heat treatment,heat action results are compared by using fast calculation math tool of heat action of arbitrarily distributed beam. The question of beam parameters expression in laser heat treatment is also discussed.
