FAYb Laser Markers
FAYb technology
For most applications in the automotive, automotive supply and metal processing industries, the requirement is for a marking system that can easily mark metal. CO2 laser markers are generally not suited for this because they emit in the 'wrong' wavelength - infrared range. The reason is simple. The physical/chemical properties of metals do not lend themselves to this marking method. Metals have a solid lattice structure and free electrons. If a laser beam impacts these electrons, a certain amount of the laser light is absorbed and interacts with the metal.The metal surface becomes heated and tends to melt or vaporize. The rest of the laser light is reflected. The degree of absorption is dependent upon the angle of incidence of the laser beam and surface properties of the metal, but mainly upon the material itself and the wavelength of the laser beam. When a CO2 laser is used to mark metal, most of the beam is reflected. Very little of the light energy is absorbed so that generally the metal just heats up a little around the laser beam. So to create a mark on metal that has sufficient contrast and that is easy to read, the requirement is for a marker that ulilizes a solid state laser such as a YAG laser. (YAG - Yttrium Aluminum Garnet), wavelength. 1.06” metres.
A further development of YAG technology is called FAYb, (Fiber Amplified Ytterbium). This laser marker system has some significant advantages compared with conventional YAG systems such as smaller housing dimensions, longer life and lower running costs. FAYb systems consume significantly less power and utilize simple air cooling with no need for complex purified water cooling systems. As an illustration the LP-V10 laser marking system from Sunx with an output power of 12 watts can mark practically any metal with extremely high visibility and quality.
