Abstract
A method for generating an at least partial fluorescent property in a material is provided. The method comprises providing the material, providing a laser, arranging the material in a beam path of the laser such that the laser can selectively section wise irradiate the material, and at least section wise irradiating a surface of the material with the laser. The at least sectionwise irradiating of the surface of the material with the laser is performed until visible traces of smoke are formed on the irradiated areas of the surface of the material, whereby a fluorescent property is generated in the irradiated areas.
