Title:
LASER TURNING DEVICE, LASER MACHINING DEVICE, AND LASER MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/084750
Kind Code:
A1
Abstract:
Provided is a laser machining device that can facilitate minute control on an incident angle of a laser beam on a dove prism. This laser turning device for turning an incident laser beam comprises: a first wedge prism that deflects the incident laser beam with respect to the optical axis thereof; a dove prism that causes the laser beam having transmitted through the first prism to rotate about the optical axis thereof; a first wedge prism rotating mechanism that causes the first wedge prism to rotate about the optical axis; and a dove prism rotating mechanism that causes the dove prism to rotate about the optical axis.
