Description
Technical Field

Background
When a solid-state laser resonator and an amplifier are used, the size of the pump light inevitably deviates from the calculation result of the design, so that the resonator or the amplifier generates a high-order mode or a diffraction ring. While components other than the central fundamental mode gaussian beam are disadvantageous. In order to obtain only the fundamental mode gaussian beam and remove components except the central basement membrane gaussian beam, the obtained beam needs to be subjected to mode selection or filtering, and finally the basement membrane gaussian beam with better quality is obtained.
Typically, a small aperture stop is used for mode selection or filtering, and a fixed aperture stop is most commonly used. In the prior art, the diaphragm structure which is used most frequently for manual coarse adjustment is used, and for a laser, in order to improve the performance of a diaphragm mode selection method, a light beam needs to be aligned with a diaphragm hole besides a hole with a proper size, so that the diaphragm hole for coarse adjustment cannot meet the adjustment requirement.
One can look at a multi-aperture rotatable diaphragm named as CN209858848U, which uses a combined diaphragm disk with multiple different apertures to meet the requirement of different sizes of laser beams for diaphragm matching, and can achieve a certain left-right adjustment by matching the disk with a long circular hole of a base in a rotating manner. However, the combined diaphragm plate can only be rotated by hand for coarse adjustment, and when the optical path deviation needs to be adjusted, the up-down and left-right adjusting directions are coupled, which brings inconvenience to the optical path adjustment, and the combined diaphragm plate does not have the pitching angle adjustment.
