Fiber lasers are divided into two main categories: continuous fiber lasers and pulsed fiber lasers. According to the power size are: continuous 5W, 10W, 20W to 400W, 1000W or more; pulse 10W, 15W, 20W, 25W, 30W to 50W. Fiber laser marking machine is the most advanced laser marking equipment in the world. It has the characteristics of good beam quality, small volume, fast speed, long working life, flexible installation and maintenance. Widely used in integrated circuit chips, computer accessories, industrial bearings, watches and clocks, electronic and communications products, aerospace devices, all kinds of auto parts, home appliances, hardware tools, molds, wire and cable, food packaging, jewelry, tobacco and military Field graphics and text markings, as well as high-volume production lines. Fiber optic lasers, the latest international, the most reliable structure, small size (about 410 * 200 * 270mm), low power consumption, no high voltage without a large water cooling system (only about 300W), beam quality, close to the ideal beam, USB interface output control, optical scanning galvanometer, high repetition rate of laser, high speed without distortion.
