A method of evaluating quality of a laser beam output of an X-Y-Z movement laser processing head of beam generator by detecting an instantaneous profile of the beam by means of dynamical laser beam analyzer, calculating values of beam stability parameter of the beam profiles, each value of the beam stability parameter corresponding to one of the laser beam profiles, comparing the beam profiles detected and adjusting mirror orientation in the generator and calculating a standard deviation of the stability parameters and adjusting condition in supplying a laser gas to the generator. |
