Laser oscillator mirror adjustment apparatus

摘要

Adjustment of the rear or output mirror of a laser oscillator is performed by pivoting a laser mirror holder about three pivot points connecting the laser mirror holder and a support bracket. The first and third pivot points form an X-axis about which the holder may be rotated and the second and third pivot points form a Y-axis about which the holder may be rotated. The first and second pivot points are mounted so as to displace the holder in a direction parallel to the central longitudinal axis of the holder. Two control motors are disposed with their actuating shafts transverse to the central longitudinal of the laser mirror holder, at opposite sides of the side surface of the holder and act against the first and second pivot points to adjust the angular alignment of the laser mirrors.
