Compared with traditional technologies, the advantages of fiber lasers in beam quality, depth of focus and dynamic parameter adjustment performance have been fully recognized. Coupled with the advantages of electro-optical conversion efficiency, process versatility, reliability and cost, the application level of fiber lasers in medical device manufacturing (especially in fine cutting and micro welding) has been continuously improved.
A giant leap is taking place in mobility. This is true whether in the automotive sector, where autonomous driving solutions are being developed, or in industrial applications using robotics and automated guided vehicles. The various components in the whole system must cooperate with each other and complement each other. The main goal is to create a seamless 3D view around the vehicle, use this image to calculate object distances and initiate the next move of the vehicle with the help of special algorithms.
The traditional laser uses the thermal accumulation of laser energy to melt and even volatilize the material in the active area. In the process, a large number of chips, micro-cracks and other processing defects will be generated, and the longer the laser lasts, the greater the damage to the material. The ultra-short pulse laser has an ultra-short interaction time with the material, and the single-pulse energy is super strong enough to ionize any material, realize non-hot-melt cold processing, and obtain the ultra-fine, low-damage processing advantages incomparable with long-pulse laser. At the same time, for the selection of materials, ultrafast lasers have wider applicability, which can be applied to metals, TBC coatings, composite materials, etc.
Compared with traditional oxyacetylene, plasma and other cutting processes, laser cutting has the advantages of fast cutting speed, narrow slit, small heat affected zone, good verticality of slit edge, smooth cutting edge, and many kinds of materials that can be cut by laser. Laser cutting technology has been widely used in the fields of automobiles, machinery, electricity, hardware and electrical appliances.
Since the invention of the world's first semiconductor laser in 1962, the semiconductor laser has undergone tremendous changes, greatly promoting the development of other science and technology, and is considered to be one of the greatest human inventions in the twentieth century. In the past ten years, semiconductor lasers have developed more rapidly and have become the fastest growing laser technology in the world. The application range of semiconductor lasers covers the entire field of optoelectronics and has become the core technology of today's optoelectronics science. Due to the advantages of small size, simple structure, low input energy, long life, easy modulation and low price, semiconductor lasers are widely used in the field of optoelectronics and have been highly valued by countries all over the world.
Fiber Laser refers to a laser that uses rare earth-doped glass fiber as the gain medium. Fiber lasers can be developed on the basis of fiber amplifiers. High power density is easily formed in the fiber under the action of pump light, resulting in laser The laser energy level of the working substance is "population inversion", and when a positive feedback loop (to form a resonant cavity) is properly added, the laser oscillation output can be formed.
