Abstract
A method for automatically adjusting an optical axis of a laser resonator. Specifically, the angle of a mirror in a laser resonator is changed in a very small stepwise increments, and the laser output before the very little change is compared to the laser output after the incremental change. If the laser output after the very small incremental change is larger than the laser output before the very small incremental change, the angle is automatically changed by a very small amount in the same direction as the previous increment. If the laser output after the very small incremental change is smaller than the previous laser output measurement, the angle is automatically changed by a very small amount in the opposite direction. Thus the optical axis of the laser resonator is adjusted automatically.
