Title:
LASER DEVICE, AND LASER PROCESSING DEVICE IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2021/145205
Kind Code:
A1
Abstract:
A laser device (100) comprising first and second laser oscillators (1), (2) that respectively emit first and second laser beams (LB1), (LB2) having first and second wavelengths, and first and second optical systems (10), (20). The first optical system (10) combines the first and second laser beams (LB1), (LB2) and transmits these laser beams (LB1), (LB2) to the second optical system (20). The second optical system (20) is configured so as to focus the first laser beam (LB1) at a first focusing position (FP1) and to focus the second laser beam (LB2) at a second focusing position (FP2). The maximum angle formed by the optical axis of the first laser beam (LB1) emitted from the first optical system (10) and an outermost component of the first laser beam (LB1) differs from the maximum angle formed by the optical axis of the second laser beam (LB2) and the outermost component thereof.
