The invention discloses a semiconductor laser beam expander adjusting device. The device comprises an adjusting device, a swinging device and a fixing device, wherein the adjusting device is used foradjusting the relative distance between a concave lens and a convex lens of a beam expander to achieve the beam expanding purpose, the adjusting device comprises a placement box, two moving blocks andtwo driving devices for driving the two moving blocks to move back and forth in the placement box, and the two moving blocks are respectively used for fixing the concave lens or the convex lens; theadjusting device is arranged on the swinging device, the swinging device is used for adjusting the light-emitting optical axis of the laser to coincide with the central axis of the beam expander, andthe swinging device is detachably installed at the light-emitting opening of the laser; the swinging device comprises a supporting piece, an iron ball capable of rotating in any direction in the supporting piece and a pushing part for pushing the iron ball to rotate in any direction on the supporting piece; and the fixing device is arranged on the supporting piece, and the fixing device is used for fixing the rotated iron ball. The light-emitting optical axis of the laser can be adjusted to coincide with the central axis of the beam expander, and meanwhile, the focusing can be achieved.
Description
technical field [0001] The invention relates to the technical field of laser adjustment devices, in particular to a semiconductor laser beam expander adjustment device. Background technique [0002] In the field of laser processing, the beam expander is an indispensable lens component to change the diameter and spread angle of the laser beam. The laser beam emitted from the laser has a certain divergence angle. For laser processing, only by adjusting the beam expander to make the laser beam into a collimated beam can the focusing mirror be used to obtain a small high-power-density spot. [0003] When installing and debugging the laser system, the adjustment of the beam expander system directly affects the quality of the beam. The current conventional beam expander adjustment method is to place the designed beam expander adjustment system at a certain distance from the laser exit on the optical platform, and adjust the beam expander central axis to be consistent with the bea...
