Abstract

The invention discloses a laser beam combining device and processing equipment. The laser beam combining device comprises a laser device array and a first reflecting piece, the laser device array reflects at least two laser beams to the first reflecting piece, the first reflecting piece is provided with at least two reflecting surfaces which are in a step shape and are arranged in parallel, the reflecting surfaces both face the laser, and each reflecting surface corresponds to one laser beam; the reflecting surface of the first reflecting piece is arranged in an ascending step shape in the Y-axis direction, and the Y-axis direction is the laser beam direction after the laser beam is reflected by the first reflecting piece. In this way, the laser beam quality can be improved.

Description

technical field [0001] The application belongs to the field of laser technology, and in particular relates to a laser beam combining device and processing equipment. Background technique [0002] With the rapid development of the manufacturing industry, people's requirements for processing technology are getting higher and higher. Semiconductor lasers have the advantages of compact structure, light weight, easy integration, long life, low cost, and the wavelength is in the high absorption band of metal materials, and are widely used in processing technology. The existing continuous high-power semiconductor lasers are packaged by bars, and multiple laser units with micro-channel refrigeration structures are stacked in the vertical direction to achieve high power output. However, limited by the thickness of the microchannel cooler structure itself, the distance between the beams of adjacent laser units is too large after collimation, and the laser energy density is small, res...
