Title:
DIRECT DIODE LASER MACHINING DEVICE AND SHEET METAL MACHINING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/059915
Kind Code:
A1
Abstract:
A direct diode laser machining device is provided with: a laser oscillator that emits multi-wavelength laser light; a transmission fiber that transmits the multi-wavelength laser light emitted by the laser oscillator; and a laser machining device that condenses the multi-wavelength laser light transmitted by the transmission fiber and machines a workpiece. The light intensity distribution in the thickness direction of the workpiece has a plurality of peaks that are based on chromatic aberration in the multi-wavelength laser light and the wavelength dependence of the emissivity of the workpiece.
