A dual-axis rotation angle synchronous precision adjustment device

Abstract

The invention relates to the technical field of laser, and in particular relates to a biaxial rotation angle synchronous precision adjustment device which comprises an adjustment frame bracket, a left independent adjustment frame, a right independent adjustment frame and a combined adjustment frame. The adjustment frame bracket supports the whole device, and encapsulates the whole device. Left and right independent adjustment frames are fixed on shafts, and can rotate alone. The rotation angles can be respectively adjusted. Through the shaft rotation, the rotation angle of the whole adjusting frame is driven. The combined adjustment frame can simultaneously rotate left and right independent adjustment frames in the same direction or opposite directions through the connection of wire ropes and the shafts. Two independent adjustment frames can be accurately and simultaneously adjusted in the same direction or opposite directions. According to the invention, the combined adjustment frame is used to realize angle synchronous precision adjustment; the independent adjustment frames are respectively adjusted alone, so that the angles are in a state; simply by adjusting the combined adjustment frame, angle synchronous precision adjustment is accurately realized; and the device has the advantages of simple adjustment process operation, synchronous adjustment and high accuracy.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a dual-axis rotation angle synchronous precision adjustment device. Background technique [0002] In the field of optical applications, when the laser passes through certain media, the laser directivity will change, which will affect the subsequent optical path of the laser, which is not conducive to the application of the laser. Especially in the process of laser tuning nonlinear frequency conversion, the change of laser wavelength will lead to the change of the refractive index of light in the medium, which will lead to the change of laser optical path. If there is no laser pointing compensation, it is difficult to realize its precise application. In order to realize pointing compensation in the process of tuning laser nonlinear frequency conversion, the main method used by professionals in the field is to use two pieces of the same nonlinear crystal with the same cutting angle ...
