ABSTRACT:
In a system for adjusting a laser oscillator, a laser beam from a laser oscillator is detected by a power detector 22 and one of the resonant mirrors is tiltably supported by a tilting mechanism. Power signal from the detector is sampled and sampled signals are averaged by a central processing unit to obtain power average values. The power average values are compared with a power distribution curve which relates to a tilting angle of the resonant mirrors. Thus, the central processing unit determines a control value corresponding to the tilting angle of the resonant mirrors.
