Abstract

The invention provides a mold scrambler. The mold scrambler comprises a base, a rotary extrusion block and a rotary driving mechanism, wherein the right end of the rotary extrusion block is rotationally connected with the base along the front-back axis. The base is provided with an extrusion part opposite to the rotary extrusion block up and down; the rotary driving mechanism is arranged on the base and is in power coupling connection with the rotary extrusion block so as to drive the rotary extrusion block to rotate towards the extrusion part, and the optical fiber is extruded up and down through the rotary extrusion block and the extrusion part; and the extrusion surfaces of the rotary extrusion block and the extrusion part for extruding the optical fiber are concave-convex surfaces which are matched with each other. According to the mode scrambler provided by the invention, the optical fiber is swung and extruded through the mechanical structure of the mode scrambler, so that the mode balance of laser transmission in the optical fiber is broken, the inter-mode coupling effect is enhanced, the transmission and exchange of energy are controlled, the effect of adjusting the laser beam quality is achieved, and finally, laser with ideal beam quality is output.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a mode scrambler. Background technique [0002] The output power of high-power fiber lasers is closely related to the core diameter of the fiber: in order to prevent possible optical damage and nonlinear effects on the end face of the fiber under high power, as the laser power increases, the diameter of the fiber will generally increase. The increase, but at the same time the thick core will cause the beam quality of the output laser to decrease. Contents of the invention [0003] The invention provides a mode scrambler, which is used to solve the problem that the laser beam becomes worse when the diameter of the fiber core is increased to increase the laser power of a high-power laser. [0004] The invention provides a mold scrambler, which includes a base, a rotary extrusion block and a rotary drive mechanism; [0005] The right end of the rotating extrusion block is...
