Abstract

The invention discloses a high-power laser Donut mode shaping device and a shaping lens. A reflecting surface of the shaping lens is in a shape with a protrusion at the middle part and a recess at theperiphery in whole; the reflecting surface is formed by rotating around a vertical straight line through a first bus; the first bus is a section of arc line; the curvature radius of the first bus is4200 mm; the vertical straight line penetrates through the lower end point of the first bus; a vertical distance between the upper end point of the first bus and the upper end point of the first bus is 0.00625 mm; and the central angle of the first bus is 0.04 degree. The Donut mode shaping device comprises the shaping lens and a high-power radio frequency slab CO2 laser, wherein the high-power radio frequency slab CO2 laser is used for outputting a light beam with a Gaussian mode, and the light beam is input into the shaping lens. The high-power laser Donut mode shaping device and the shapinglens are suitable for occasions with the wider weld width.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a high-power laser Donut mode shaping device and a shaping mirror. Background technique [0002] The Gaussian mode is the most typical output mode in various types of lasers and is the most common mode in laser applications. However, with the wide application of lasers in various fields, many new requirements have been put forward for the mode distribution of laser beams. And the unique property of the Donut mode, the annular energy distribution, has the ability to carry the orbital angular momentum corresponding to the optical axis. In the processing of high-power slab lasers, in order to reduce the damage of the high-power fundamental mode Gaussian beam in the center of the lens, it is suitable for the occasion with a wide weld width, and the Donut mode is the best choice. The output system of the existing Donut mode generally has a complex structure and is not easy to process...
