Abstract:

Subject of the study. The efficiency of the laser cleaning system with an air-cooled terminal device based on a 500-watt five-channel single-mode fiber laser. Aim of study. Development of a compact laser cleaning system based on a 500-watt five-channel single-mode fiber laser with air-cooled. Method. The use of the source that makes it possible to increase the total area of focused beams with an abovethreshold pollution removal rate by a multiple of the number of combined lasers, while maintaining the quality of laser radiation. The laser beam intensities in the processing zone were modeled in the ZEMAX software environment, and the diffraction size and aberration pattern relationships were modeled in a sequential editor. Main results. The optical scheme of the device with air-cooling has been developed with a laser gun and removal of cleaning elements, and critical heat dissipation points
have been analyzed, according to this, the supporting element of the gun is designed in the form of an effective radiator. With this in mind, the design of a commercial laser cleaning system is proposed. In the laser system, the scanning laser channels are focused into five lines with different periods. Practical significance. A robust laser cleaning system has been developed for use in metalworking applications large industrial facilities. This allows for the delivery of radiation over a significant distance from the source.
