CUTTING METHOD USING A LASER HAVING AT LEAST ONE YTTERBIUM-BASED FIBER, IN WHICH AT LEAST THE POWER OF THE LASER SOURCE, THE DIAMETER OF THE FOCUSED BEAM AND THE BEAM QUALITY FACTOR ARE CONTROLLED

Publication number: 20090218326

Abstract: The invention relates to method for cutting a part using a laser beam, involving the use of laser beam generation means comprising at least one ytterbium-based fibre having a wavelength of between 1 and 4 ?m in order to generate the laser beam. The laser beam is selected to have a power of less than 100 kW, a power density of at least 1 MW/cm2, a focused beam diameter of at least 0.1 mm and a quality factor (BPP) of less than 10 mm·mrad.
