Mirror regulation device for fast axial flow gas laser

Abstract

The invention discloses a mirror regulation device for a fast axial flow gas laser, which comprises a fixed plate, a mirror regulation plate and a mirror room, wherein the fixed plate is fixed on an end plate of a resonant cavity of the laser; the mirror regulation plate is arranged on the fixed plate; the mirror room is arranged on the mirror regulation plate; a lens is arranged in the mirror room; a gas curtain pressure cover is arranged on the mirror room; the mirror regulation plate is connected with a screw hole of the fixed plate by long screws; differential screws and matched screw rods are arranged on the mirror regulation plate; the differential screw is in threaded connection with the mirror regulation plate; the front end of the matched screw rod is in threaded connection with the interior of the differential screw, and the tail end of the matched screw rod is pressed against a supporting pin fixed on the fixed plate; and the mirror regulation plate is pressed against one side, provided with the supporting pins, of the fixed plate. The mirror regulation device has the characteristics of stable performance, mounting simplicity and convenience of regulation, and ensures the stability of laser output.

Description

technical field [0001] The invention relates to a mirror adjustment device for a laser, in particular to a mirror adjustment device for an axial fast flow gas laser. Background technique [0002] The mirror adjustment device is one of the important components of the optical system of the axial fast flow gas laser, which is mainly composed of the mirror adjustment plate, the fixed plate, the mirror house and other components. For high power lasers, the stability of the reflective and partially reflective optics used is important. If the optical system has unstable factors, it will cause changes in laser power, mode, divergence angle, optical axis and focus position of the processing point, and stable processing cannot be performed. Therefore, a stable mirror adjustment device is very important. [0003] The lens of the laser mainly includes a total reflection mirror and an output mirror. The resonant cavity of the laser is well matched with the lens, so that the laser outp...

AI Technical Summary

Problems solved by technology

During the loading and unloading process of the mirror house, the relative position between the mirror adjustment plate and the fixed plate will also be affected. After the lens is reinstalled, the optical path needs to be readjusted, otherwise, the stability of the laser output cannot be guaranteed.
