ABSTRACT:
The present invention relates to a laser beam emitting apparatus using a semiconductor laser or the like and a method of driving a laser light source. An object of the present invention is particularly to provide a laser beam emitting apparatus capable of controlling a laser output with efficiency and a method of driving a laser light source. The laser beam emitting apparatus comprises an optical resonator, the laser light source and pulse driving means. The optical resonator comprises at least a laser crystal and an output mirror. The laser light source pumps the optical resonator and the pulse driving means drives the laser light source. The pulse driving means can change the period and the duty ratio or the like of a drive pulse or pumping pulse so as to control a laser output produced from the laser beam emitting apparatus.
