Fiber Laser Marker

Compared with traditional gas lasers, solid-state lasers, semiconductor lasers and dye lasers, fiber lasers have rich doped rare earth ion energy levels, wide doped rare earth ion energy levels, diversified types of doped rare earth ions, low fiber manufacturing costs, small fiber structure and easy to operate, large surface area/volume ratio of fiber geometry, high weighing efficiency, easy connection with optical fiber transmission systems, wide optical fiber incineration spectral range (455-3500nm), no strict requirements for incident Lipu light phase matching, fast heat dissipation, Low loss, high conversion efficiency, low Power of Kuriura Min value, high laser brightness and high peak laser power, good output beam quality, good monochromaticity, stable directionality, wavelength tunable, easy to achieve single mode, single frequency operation and ultra-short pulse and other advantages.

Fiber laser to the optical fiber as the gain medium, the output laser beam quality is mainly determined by the fiber core diameter and numerical aperture, due to the large surface area and volume ratio of the fiber, it is easy to effectively manage its thermal effect at high power output. At the same time, due to the large surface area to volume ratio of the fiber in the fiber laser, the heat dissipation performance is also very good, so the thermal lens effect is almost non-existent. Therefore, fiber lasers can achieve a high beam quality close to the diffraction limit at high power output compared to conventional solid-state lasers. In terms of electro-optical conversion efficiency, the electro-optical conversion efficiency of fiber lasers can be as high as 28%, which is much higher than the electro-optical conversion efficiency of 15% of the YAG lasers pumped by semiconductors and 10% of the electro-optical conversion efficiency of CO2 lasers, and also higher than the electro-optical conversion efficiency of lasers for disc machines. The device structure of fiber laser is simple, small in size, flexible and convenient to use. Double-clad fiber laser Due to the use of soft doped fiber itself as the laser medium, the pump source is also the use of small and easy to modular high-power semiconductor laser, so the stability is good, the size is small, flexible and convenient to use.
Fiber laser also has the advantages of wavelength tunable, high reliability, maintenance-free, pigtail output and long service life, etc., is a new type of high-quality laser light source, has attracted widespread attention [3], has formed fiber laser product types include: continuous laser, pulse laser, single polarization laser, single frequency laser, ultra-short pulse laser and white ultracontinuous light source. Its applications cover material processing, medical, printing, radar, communications, laser cutting, precision machining, printing rollers, metal non-metallic drilling/cutting/welding, industrial shipbuilding, large-scale infrastructure, aerospace, military defense and security and other fields, the market demand is also increasing. According to statistics, in 2010, fiber lasers have accounted for about 25% of the entire laser market, with annual sales of nearly 700 million US dollars. With such a huge market demand, the research of fiber lasers has become a research hotspot in the field of lasers.
