Development trends of fiber laser marking machines:

The development trends of fiber laser marking machines are mainly reflected in the following aspects:

1. Performance improvement: The improvement of the performance of the fiber laser marking machine itself includes improving the output power and conversion efficiency, optimizing the beam quality, shortening the length of the gain fiber, improving system stability and making it smaller and more compact.

2. Development of new fiber lasers: In the time domain, ultra-short pulse mode-locked fiber lasers with smaller duty cycles have always been a hot spot in the laser field, and high-power femtosecond pulse fiber lasers have been long-term pursuits. Target. In the frequency domain, broadband output and tunable fiber lasers will become a research hotspot.

3. Expansion of application fields: With the emergence of new materials and new application requirements, fiber laser marking machines will continue to expand their application fields. Ceramics, for example, is one of the fastest growing materials in laser processing and is particularly important in the manufacturing of semiconductor parts and circuit boards. However, many traditional marking technologies are not suitable for ceramic materials, so fiber laser marking machines have broad application prospects in the field of ceramic processing.

4. Intelligence and automation: With the advancement of Industry 4.0 and intelligent manufacturing, the degree of intelligence and automation of fiber laser marking machines will continue to increase. For example, by introducing machine vision and artificial intelligence technology, automatic identification, tracking and marking can be achieved, improving production efficiency and processing accuracy.

Environmental protection and sustainable development: With the improvement of environmental awareness, the development of fiber laser marking machines will pay more attention to environmental protection and sustainable development. For example, green manufacturing can be achieved by using renewable energy, reducing waste emissions, and adopting low-cost and high-efficiency fiber lasers.

In general, the development trend of fiber laser marking machines is multi-faceted, covering aspects such as performance improvement, new laser research and development, application field expansion, intelligent automation, environmental protection and sustainable development. In the future, with the advancement of science and technology and the growing demand for applications, fiber laser marking machines will continue to develop and innovate, providing more efficient, accurate, and environmentally friendly solutions for industrial production and processing fields.

Fiber laser marker machine is a laser that uses rare-earth element-doped glass fiber as the gain medium. Fiber laser marking machine has become a hot spot in laser physics research in recent years, and it is unanimously considered to be a new generation of products that may completely replace solid-state lasers. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, it is easy to form high power density in the fiber, resulting in the "number inversion" of the laser energy level of the laser working material. When a positive feedback loop is properly added ( form a resonant cavity) to form a laser oscillation output [1]. The fiber laser marking machine uses a laser beam to mark permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the desired etching pattern. , text, barcode and other graphics

development trend:
(1) Improvement of the performance of the fiber laser itself: how to improve the output power and conversion efficiency, optimize the beam quality, shorten the length of the gain fiber, improve the system stability and make it more compact and compact is the focus of future research in the field of fiber lasers.
(2) Development of new fiber lasers: In the time domain, ultrashort pulse mode-locked fiber lasers with smaller duty cycles have always been a hot research topic in the laser field, and high-power femtosecond pulsed fiber lasers have been a long-term pursuit. The goal. In the frequency domain, broadband output and tunable fiber lasers will become a research hotspot.
The research of fiber lasers has been started since the late 1980s. Because of its ability to generate ultra-short pulses, it has a very broad application prospect, so countries around the world have shown great enthusiasm for the research of fiber lasers. Compared with other types of lasers, fiber lasers have the outstanding advantages of high reliability, simple structure, low price, and high conversion efficiency.
Domestic research in this field is also carried out relatively early, and many research results have been achieved both theoretically and experimentally. However, compared with foreign countries, there is still a big gap. In particular, there are relatively few studies on high-performance fiber lasers, and the practical work is far from enough, and the effect is not very satisfactory. Therefore, it is necessary to further strengthen the research on passive mode-locked fiber lasers.
In 1963, Snitzer reported for the first time Nd-doped fiber lasers, which opened a wave of research on fiber lasers. Especially in recent years, with the progress in fiber design and fabrication, the output of fiber lasers has been increasing, and the CW output power of a single fiber device has risen from 100 watts to kilowatts. At the same time, improvements in fabrication techniques for high-quality fibers with large cladding diameters and large numerical apertures make it easy to achieve efficient coupling to diode pump power.
The most significant advantage of fiber lasers is their extremely high pumping efficiency. In general, the pump conversion efficiency is 70%-75%, which is much higher than that of industrial diode-pumped solid-state lasers (DPSSL). Such high conversion efficiency reduces the cooling and power requirements of the laser system, enables a more compact structure than conventional solid-state lasers, and the all-fiber structure provides a very robust and highly reliable package design. Furthermore, fiber lasers can significantly enhance the output beam quality.
Another important advantage is that fiber laser technology can greatly extend device life (compared to DPSSL), which has led to increasing investment by industrial laser companies focusing on fiber lasers, because the long-term reliability operation from the application level is very high. important. Fiber lasers also have other advantages: because the laser medium of fiber lasers is itself a waveguide medium, the combination efficiency is high; fiber lasers can be easily and efficiently connected to fiber transmission systems; the fiber core can be made very thin, which can achieve high power density; The heat dissipation performance of the fiber is good, so the fiber laser has a high conversion efficiency and a very low threshold value; the output wavelength of the fiber laser covers a wide range, from 400 to 3400nm, which can meet the application needs of various aspects. It has good application prospects in military, medical and other fields.
