The best way for the practicality and industrial development of fiber laser cutting machine is the only technical specification that has entered into productization and industrial development at this stage. The development trend of all fiber laser involves five core technologies: double clad fiber, insulating layer pump coupling, fiber grating, power multi module pumped semiconducting laser and fiber laser.

Five key technologies of optical fiber metal laser cutting machine

1. Special optical fiber technology

All fiber lasers must use several special optical fibers, such as double clad active fiber, double clad sensitive fiber and kinetic energy transmission fiber. With the continuous improvement of power, the technical standards for special optical fibers are getting higher and higher. Therefore, the development trend of special optical fibers will play a key role in the development trend of fiber lasers. A new generation of special fibers, which means photonic crystal fibers, will be gradually used in the development trend of fiber lasers.

The development trend of special optical fiber will make the active optical fiber have higher gain value, higher power density and more reasonable digestion and absorption of pump light; It will make the fabrication of optical fiber sensors easier, the reliability of optical fiber sensors stronger, and the main use of optical fiber sensors in fiber lasers more common; It will enable the kinetic energy transmission fiber to transmit higher output power, can transmit high-power lasers at a long distance, and can continuously expand the range of optical wavelengths that can be transmitted; It will make the pump coupling easier to maintain, and can bear higher pump output power and lower consumption.

2. Fiber Bragg Grating Technology

In the all fiber laser, the function of fiber grating at this stage is to generate a resonator for the data signal laser generator of the reflective surface fiber core. However, with the further development trend of fiber laser technology, the fiber grating laser generator will have a new main purpose, and further put forward new challenges to the fabrication technology of fiber grating. Among them, one of the most concerned areas is, High quality fiber gratings are fabricated on large core diameter multimode fibers.

3. Insulation layer pump coupling technology

The insulating layer pumping coupling technology of all fiber lasers has an inestimable effect on determining the characteristics and level of fiber lasers. The fiber pump coupler and fiber output power generation components used to power all fiber lasers are all applied under very high output power standards. Their coupling must be high, their consumption must be small, and their output power must be large. In addition, the optical keying routines must be as many as possible.

Under such a lot of limit standards, making high-quality pump coupler devices and output power generation components has a high degree of difficulty. However, there are various ways to keep them, which is an interesting technology. From the perspective of the development trend of the power fiber laser, it is also stipulated that the pump coupler should not harm and endanger the fiber core of the double clad fiber as much as possible when coupling the pump light to the internal insulation layer. Therefore, only in this way can the cascade pump be maintained without harming the generation and transmission of the data signal laser, and the output of the super power be maintained. Development Trend The development trend of pump coupling devices in the pump coupling technology room, which do the least harm to the fiber core. For the light source output power generation components, the overall goal required is to continuously improve the generated optical power.

4. The whole equipment technology of fiber laser

The whole equipment design scheme and production scheme of all fiber laser have a lot of professional knowledge, content, technology, processing technology and work experience. It is the most critical and important technology in the design scheme and production of all fiber laser, especially in today when the history of the development trend of new power all fiber laser is very short, there are also many pioneering work that must be carried out. To carry out the whole equipment design scheme and production of all fiber lasers, we must not only carry out effective design scheme towards application, but also shoulder the burden of improving the whole equipment structure and planning scheme through independent innovation. At this stage, in the global scope, the manufacturers that carry out the design scheme and production of the whole equipment of fiber laser have a lot of capital investment in independent innovation.

5. Semiconductor material pumped laser technology

Semiconductor material pumped laser is an important component of fiber laser, which is particularly important to the credibility, service life and production cost of fiber laser. The development trend is a wide bright area. The service life of semiconductor material pumped laser has already become a development trend of semiconductor material pumped laser for fiber laser.

Continuously improving the power of the individual laser generator, continuously controlling the cost and further improving the credibility are the top priorities. Among them, improving and independently innovating the packaging structure should be the key work, because the proportion of packaging cost is still high at this stage.

The whole equipment design scheme and production of the optical fiber laser cutting machine involve a lot of professional knowledge, content, technology, processing technology, work experience and Know How, which is the most critical and important technology for the design scheme and production of the optical fiber laser cutting machine. Especially in today's very short history of the development trend of new all fiber lasers, There is also a lot of pioneering work that must be carried out. To carry out the entire equipment design scheme and production of the all fiber laser cutting machine, we must not only carry out effective design schemes towards the application, but also shoulder the burden of independent innovation for the improvement of the entire equipment structure and planning scheme, and the burden of improvement and independent innovation of key components and core technologies. At this stage, The manufacturers that carry out the design scheme and production of the whole equipment of the optical fiber laser cutting machine have a lot of capital investment in independent innovation.
