With the emergence of high-power lasers on the market, laser marking machine processing technology has gained practical application. Laser marking machine technology uses laser heating to form a certain thickness of treatment layer on the surface of the material, which can improve the mechanical properties, metallurgical properties and physical properties of the material surface, thereby improving a series of properties such as wear resistance, corrosion resistance and fatigue resistance. . Fiber laser marking machine uses optical fiber as gain medium, which has a large surface area / volume ratio, which makes it have very good heat dissipation performance. Therefore, even very high power fiber lasers, the gain medium will not be damaged by heat. Generally There is no need to take special heat dissipation measures for the gain medium, and for other types of lasers, the heat dissipation problem of the gain medium needs to be carefully considered. Therefore, this feature is unique to the fiber laser marking machine .
1. Lasers for fiber laser marking machines are adjustment-free, maintenance-free, and highly stable. Traditional lasers cannot be produced without a resonant cavity, and the existence of a resonant cavity makes laser adjustment and maintenance very difficult.
For example, the CO2 gas laser marking machine laser and the solid-state laser of the semiconductor laser marking machine need to carefully adjust the optical lens set when the laser is installed. During the use, the corresponding parts must be regularly checked and maintained to ensure the normal use of the laser. The laser optical resonance of the fiber laser marking machine is completed inside the fiber. There is no optical cavity in the traditional sense, so it can achieve maintenance-free, adjustment-free and high stability. This is a qualitative breakthrough for traditional lasers.
2. High electro-optical conversion efficiency, the photoelectric conversion efficiency of traditional semiconductor solid-state lasers is very low
For example, the Nd: YAG laser marking machine laser photoelectric conversion efficiency does not exceed 3%, the semiconductor laser marking machine laser photoelectric conversion efficiency does not exceed 20%, and the fiber laser marking machine laser conversion efficiency is not less than 27%, far exceeding Traditional solid-state laser. The fiber laser marking machine laser adopts double-clad fiber pumping technology. The pump light is repeatedly pumped in the double-clad fiber to increase energy absorption, so the photoelectric conversion efficiency is high.
3． High environmental tolerance, traditional laser marking machine has high requirements on the use environment
For example, the semiconductor laser marking machine requires that the laser installation location must have appropriate shock absorption measures, while the fiber laser marking machine laser does not have the traditional optical lens group, so it can withstand shock and vibration, that is, the laser can be moved without adjusting the laser. Makes the laser site construction possible; traditional laser marking machines have strict requirements on the temperature, humidity, and dust of the laser environment, and the laser pump source of the fiber marking machine is inside the equipment, and the dust will not affect the laser pump. At the same time, the temperature and humidity requirements are also much broader, and the environmental tolerance of the fiber laser is enhanced, making it possible to operate in the field and at sea.
4． Small size and fiber transmission. The laser of fiber laser marking machine does not have complicated optical lens group, and the photoelectric conversion efficiency is higher than that of traditional laser.
Therefore, the volume of the fiber laser is significantly smaller than other lasers. The small size makes the fiber laser marking a small footprint in the airport . It can be conveniently integrated into a complete set of processing equipment, and can also be conveniently transported, which is convenient for different field operations.
