Fiber lasers have become a hot topic in laser physics research in recent years, and it is unanimously recognized as a new generation of products that are likely to completely replace solid-state lasers. A fiber laser refers to a laser using a rare earth-doped glass fiber as a gain medium. The fiber laser can be developed on the basis of a fiber amplifier: under the action of pump light, a high power density is easily formed in the fiber, resulting in a laser of the laser working substance. The energy level “particle number inversion” can form a laser oscillation output when a positive feedback loop (constituting a resonant cavity) is appropriately added.
Fiber laser marking machines use laser beams to mark permanent surfaces on a variety of different materials. The effect of marking is to expose the deep material by evaporation of the surface material, or to “engraving” the physical changes of the surface material by light energy, or to burn some of the material by light energy to reveal the desired etching pattern, text, barcode and other graphics.
TASTELASER fiber laser marking system combines the industry experience and application knowledge for years. It has profound experience in industries of leather, paperboard, textile, mobile phone, smart home and LED lighting etc. The innovative products are not only able to meet many present demands for customers in manufacturing and research industries, but also satisfy their future demands.
Fiber laser marking machines can process a variety of metal and non-metal materials. In particular, marking high hardness, high melting point and brittle materials is more advantageous. It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small. High processing efficiency, computer control, and easy automation. Widely used in integrated circuit chips, computer accessories, industrial bearings, watches, electronic and communications products, aerospace equipment, various automotive parts, home appliances, hardware tools, molds, wire and cable, food packaging, jewelry, tobacco and military matters, etc.
The research of fiber lasers has been started since the late 1980s. Because of its ability to produce ultrashort pulses, it has a very broad application prospect. Therefore, countries around the world have shown great enthusiasm for fiber laser research. Compared with other types of lasers, fiber lasers have outstanding advantages such as high reliability, simple structure, low price, and high conversion efficiency.
The performance improvement of fiber laser itself: how to improve output power and conversion efficiency, optimize beam quality, shorten gain fiber length, improve system stability and make it more compact is the focus of future research in fiber laser field. The development of new fiber lasers: In the time domain, ultrashort pulse mode-locked fiber lasers with smaller duty cycle have been the hotspot in the field of laser research. High-power femtosecond pulse fiber lasers have been the long-term goal.
The most significant advantage of fiber lasers is their extremely high pump efficiency. Pump conversion efficiency is typically 70%-75%, which is much higher than industrial diode-pumped solid-state lasers. This high conversion efficiency reduces the cooling and power requirements of the laser system, is more compact than conventional solid-state lasers, and the all-fiber construction provides a very rugged and highly reliable package design. Moreover, fiber lasers can significantly enhance the beam quality of the output.
Another important advantage is that fiber laser technology can greatly extend the life of the device, which has made industrial laser companies concerned with fiber lasers increasingly investing because of the long-term reliability of the application level. Fiber lasers also have other advantages: since the laser medium of the fiber laser itself is a guided wave medium, the efficiency of the process is high; the fiber laser can be easily connected to the fiber transmission system efficiently; the core can be made very fine and can achieve high power density; The fiber has good heat dissipation performance, so the fiber laser has high conversion efficiency and low enthalpy. The output wavelength of the fiber laser covers a wide range from 400 to 3400 nm, which can meet various application requirements in business, communication, and military, medical and other aspects have good application prospects.
Many people don’t know much about laser marking machines, they don’t know whether their industry will use them. In fact, laser marking machines are widely used. For example: in the hardware industry, measuring tools, sanitary ware, stainless steel tableware, medical equipment, luggage, leather bags, gift industry such as metal gifts, wooden boxes, U disk, notebooks, metal watch cases, watch bottoms, glasses frames, instrumentation and panels in the watch industry, as well as mobile phone cases and electronic components in the packaging industry and electronic communication industry.
Therefore, through these we know that the laser marking machine has a broad market prospect, and this market has yet to be redeveloped and re-excavated, so laser marking machine companies should aim high and achieve more. So doing a good job in the moment, looking to the future is a good start to cater to the market and create performance. TASTELASER has always adhered to high standard.
