Introduction: Semiconductor laser marking machine is the wavelength of 0.808um semiconductor laser diode-pumped Nd: YAG medium, the media have a lot of inversion to form the giant pulse laser output wavelength 1.064um in the role of Q-switch, electro-optical conversion efficiency high. Computer-controlled laser beam galvanometer by changing the optical path of the laser beam automatic marking. Such machines have a small spot, high precision marking, spot reliable, fast, easy to debug marking effect, and low power consumption, low cost, an important optical components are imported from Europe and America, the optical system is fully sealed structure to meet the continuous 24-hour full-load operation. Features: good stability using semiconductor technology to replace traditional power vacuum technology. Excitation source to replace the use of high-power semiconductor array krypton lamp, greatly extending the life of the product and the stability of the system. High efficiency diode-pumped laser marking system output beam quality is much higher than ordinary laser system (most line width can reach 0.015mm), processing efficiency and quality than the same power output krypton lamp-pumped lasers. High precision diode-pumped laser marking system output beam quality more nearly ideal model, the quality of high-precision laser marking optional different aperture (0.8 ~ 2.6mm) of the diaphragm, available in different sizes spot output, ensuring fight target accuracy. More suitable for ultra-fine processing, minimum character size up to 0.2mm, precision laser marking to a new order of magnitude. Easy to operate Windows XP operating system, marking software is simple, friendly interface with powerful graphics and processing speed self ultra-fine optics, the galvanometer faster than traditional laser systems. Low power consumption semiconductor laser marking system efficient semiconductor matrix, laser conversion efficiency greatly improved, general system power consumption does not exceed 1500W, only a quarter of the same power krypton lamp-pumped laser systems. High reliability and high system integration and a half, no high-voltage power supplies, high voltage devices, greatly ensure system reliability. No supplies only pure water recycling and general filter, no need to replace krypton lamps and other supplies, reduce system operating costs. Small volume of highly integrated control system help customers make better use of plant space (the whole area of ??less than 1.5M2).
