1. The advantages of high-power fiber lasers
At present, the continuous output power of commercial fiber laser pointer has risen to the order of several kilowatts or even 10,000 watts. Compared with general lasers, fiber lasers have many unique advantages, such as good beam quality; small size, light weight, and maintenance-free; wind cooling, simple and easy to operate;
Low operating cost, can be used in industrial environment; long life, high processing accuracy, fast speed; high power conversion efficiency, can realize intelligent, automated, flexible operation, etc. Based on the above advantages, its application fields have been extended to the laser cutting and laser welding of metal and non-metal materials such as automobile manufacturing, shipbuilding and aviation manufacturing.
2. Industrial applications of high-power fiber lasers
In terms of industrial processing, laser processing technology is a processing technology that uses the characteristics of the interaction between laser and matter to cut, weld, surface treatment, perforate and micro-process materials. It is the most promising market for high-power fiber lasers. Application areas. Compared with mechanical processing, laser processing has the advantages of wide processing objects, non-contact processing, low pollution, high speed, and automatic control. It is known as “the common processing method of future manufacturing systems.
Compared with traditional high-power lasers, ytterbium-doped high-power fiber green laser pointer with operating wavelengths in the range of 1060-1200 nm have the advantages of high conversion efficiency, good beam quality, long maintenance periods, and low operating costs. Its extremely high efficiency and The power is comparable to traditional YAG lasers in terms of material processing.
In the field of laser marking, due to the high beam quality and positioning accuracy of fiber lasers, integrated circuit manufacturers have begun to replace the inefficient cq laser and flash lamp pumped Nd: YAG pulse laser marking systems with fiber laser marking systems. Making small nameplates on semiconductor chips and packaging, it is also commonly used to mark plastics and metals; in the field of welding, the power required for laser soldering and sintering is 50-500 W, and metal welding and brazing are 5-20 kW, high-power fiber laser can fully meet the requirements.
