Optical static method and apparatus for laser irradiation of a metallic product and its application to the magnetic bleaching treatment

摘要

The process of treatment by laser irradiation in a bath of the surface of a product of magnetic material is to carry out, simultaneously, on an entire line corresponding to a width of the treated product, the laser irradiation. & br / the device is fitted with a source of laser radiation and comprises an optical combination (20) arranged between this source (10) and the product (p) and made of two lenses (21, 22), one which is divergent and the other convergent, and whose axes are orthogonal geometric so as to transform the beam (f) coming from the curve (10) in a line (t) is relatively narrow oriented approximately transversely to the direction of movement. & br / application to the metal sheets to use electromagnetic.
