Conical phase locking carbon dioxide laser

Abstract

The invention discloses a conical phase locking carbon dioxide laser, and belongs to the fields of optical engineering and laser application. The conical carbon dioxide laser and axially-symmetric output beams are subjected to phase locking, and then convergent beams form intense coherent superposition, so the conical phase locking carbon dioxide laser has the laser processing efficiency and property sufficiently close to that of an axial flow carbon dioxide laser or even exceeding, and has the advantages in the aspects of device volume and use convenience. The conical phase locking carbon dioxide laser has good compactness the same as a cylindrical CO2 laser and a flat waveguide CO2 laser, the quality and the coherence of the output beams of the conical phase locking carbon dioxide laser are higher than those of the cylindrical CO2 laser, and the compactness and the output level quality of the conical phase locking carbon dioxide laser are higher than those of the flat waveguide device. After being processed by a convergence system, the output beams of the conical phase locking carbon dioxide laser can be conveniently applied to surface treatment, welding, cutting, perforating and the like of metal and nonmetallic materials; and the conical phase locking carbon dioxide laser can become an important device for laser processing.

Description

technical field [0001] The invention relates to the field of optical engineering and laser application, mainly a construction method and device of a phase-locked high-power carbon dioxide laser composed of a conical discharge area and related optical elements. The output beam of the conical phase-locked carbon dioxide laser can be conveniently applied to the surface treatment, welding, cutting, drilling, etc. of metal and non-metal materials after being processed by the converging system, and can become an important equipment for laser processing. Background technique [0002] Laser processing is to use the characteristics of laser's excellent directionality, high output power and coherence to perform high-precision and rapid processing of metal and non-metal materials. The lasers used for processing were mainly pulse-oscillating ruby ​​lasers and neodymium glass lasers before 1967. Afterwards, with the improvement of the output power of continuous-oscillating carbon dioxide...

AI Technical Summary

Problems solved by technology

Although the output beam of the carbon dioxide laser included in the patent (Application No.: 2007100483280) is axisymmetric, it is less likely that there is a definite phase relationship between each part of the beam. Poor and cannot form strong coherent superposition, at least cannot form continuous coherent superposition, so it will have adverse effects on processing efficiency, characteristics and stability in laser processing
