ROTATING OPTICAL PATH BEAM DEVICE, METHOD FOR USING SAME, AND ROTATING OPTICAL PATH BEAM SYSTEM

WIPO Patent Application WO/2021/120594

A1

A rotating optical path beam device (100), a method for using same, and a rotating optical path beam system. The rotating optical beam device (100) comprises a wave plate rotating mechanism (10), a two-dimensional scanning mechanism (20), a first adjusting lens group (30), a second adjusting lens group (40), a reflector (50), and a focusing lens group (60), which are sequentially distributed along the optical axis. The wave plate rotating mechanism (10) is configured to rotate an incident laser beam at high speed so as to form polarization states consistent in various directions, so that the polarization state of the laser beam is kept in radial distribution. The two-dimensional scanning mechanism (20) is configured to scan the X-Y plane of the laser beam to form a ring that rotates about the optical axis required for processing. The first adjusting lens group (30), the second adjusting lens group (40), the reflector (50) and the focusing lens group (60) are configured to control the size of the ring and the angle of the beam.
