Title:
LASER MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/012379
Kind Code:
A1
Abstract:
This laser machining device is provided with: a laser oscillator that outputs laser light (L) having a plurality of wavelengths; a transmissive diffractive optical element (21) which the laser light (L) passes through; a machining lens (3) that collects the laser light (L) passed through the transmissive diffractive optical element (21); a distance adjustment mechanism (31) that changes the distance between the transmissive diffractive optical element (21) and the machining lens (3); and an angle adjustment mechanism (32), which changes the angle of the transmissive diffractive optical element (21), and performs switching between a state wherein the laser light (L) is dispersed by the transmissive diffractive optical element (21), and inputted to the machining lens (3), and a state wherein the laser light (L) is inputted to the machining lens (3) without being dispersed by the transmissive diffractive optical element (21).
