Title: METHOD AND ARRANGEMENT FOR LASER-BASED PROCESSING
Abstract:
Method (200) for non-contact processing of fibrous material comprising providing (206) a blank of fibrous material, providing (204) a laser processing equipment, said equipment being configured to exhibit a laser emission substantially at a wavelength falling within a range from about 2 to about 10.4 10.3 microns, and subjecting (210, 210A, 210B) the blank to a laser beam of the laser processing equipment to produce a target design therefrom, incorporating directing the beam to the blank following a selected pattern in accordance with the target design. Arrangement (100) for implementing the method is presented.
