Description

technical field [0001] The invention relates to a flexible processing laser device for laser cleaning and laser strengthening, which belongs to the application fields of laser cleaning, laser shock strengthening and laser industrial processing technology. Background technique [0002] With the development of laser cutting, laser welding, laser cleaning, laser shock strengthening, laser underwater operation and other applications, more requirements are put forward for the processing of laser processing parameters. Some fields such as laser cleaning and laser shock strengthening require short pulse width laser The pulse energy has specific application requirements. The current fiber laser material processing mainly uses a single fiber to transmit the laser beam to the material surface and move the laser head to process the material. The laser beam with large energy, short pulse width and ultra-short pulse width is coupled and transmitted by fiber. Limited by the laser damage t...

Problems solved by technology

The processing and maintenance of key components in the aircraft and aerospace fields also rely on laser cleaning and impact strengthening technology to improve safety and reduce operating costs. The fields that require high energy use mainly rely on the transmission of light guide arms, while the transmission of laser light by light guide arms does not It is convenient to realize flexible and flexible processing in some application fields. It is difficult to apply in narrow or curved working spaces, and the quality of the output laser beam is easily deteriorated due to the deformation of the internal mirror of the light guide arm.
