<p><P>PROBLEM TO BE SOLVED: To change the pulse energy and the repetition frequency of laser light while maintaining superior processing accuracy by using a single laser light source apparatus. <P>SOLUTION: After fiber amplifiers 153 and 155 amplify laser light emitted from a seed LD151, a solid-state laser amplifier 158 amplifies the laser light. A controller 160 controls excitation light, which excites a solid-state laser medium of the solid-state laser amplifier 158, so as to apply the excitation light to the solid-state laser medium in synchronization with the laser light, and also controls the intensity of the excitation light in accordance with the repetition frequency of the laser light so that the power of the excitation light per unit time becomes a predetermined value. The present invention is applicable, for example, to a laser repair apparatus. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
