With continuous improvement of laser technology, high power diode laser has shown significant technical advantages on cladding, repairing, alloying, heat treatment (quenching, annealing) of metal materials, for which the laser technology has got more and more applications and attentions. Comparing with the traditional lamp pumped YAG solid state laser and CO2 laser, diode laser has the advantage of higher processing efficiency, smaller volume, lighter weight (<20kg), and higher photoelectric conversion efficiency (~50%). Recently, Focuslight has launched second generation high power long working distance diode laser head for material surface processing. The center wavelength of the new released product is 976nm; the working distance is 300mm and its output power can reach up to 5000W. Besides, it can output millimeter level rectangular or square spot, and the output spot energy is almost flat-topped. The new released laser head also has the following features: ?300mm long working distance?greatly improves the reliability and application range of the laser head, and reduces the frequency of changing protection window, which helps to reduce the use-cost. ?User-friendly output protection and control system?make the laser head more robust and convenient. ?Integrated cooling system?makes the whole system more compact; ?Automatic purification function of the cooling system?reduces the frequency of changing deionized water; ?Reliable water and electricity connectors?allow long-term safe and stable operation of the laser head. High power diode laser can be widely applied in the industry of metallurgy, molds, machinery manufacturing, petroleum & chemical industry, light industry, energy and transportation. Besides, Focuslight is also capable of providing customers with the integrated laser solutions including matched driver, output protection & control system, as well as cooling system so that customers only need a manipulator or a machine tool to use it. What is more, Focuslight can also provide customers with professional training, installation and rapid after-sales services.
