FIELD: optics.
SUBSTANCE: method of adjusting of resonator mirrors comprises mounting mirrors in holders with pressing them at three points on bearing part of resonator and matching working surfaces of mirrors. Adjustment is carried out in two stages. At first stage - when adjusting resonator - angle of deviation between working surfaces of mirrors is measured. On this basis place of holder surface finishing is determined. After that holder surfaces are matched by means of finishing them on grinding wheel. At second stage - when adjusting laser - quality of first stage adjustment is checked by measuring radiation energy and spot radiation intensity distribution in far zone. On this basis degree of accuracy of alignment of working surfaces of mirrors is determined, and, if necessary, holder surfaces are finished.
EFFECT: providing of high accuracy of alignment of working surfaces of mirrors when adjusting resonator.
