Laser, due to its high brightness and coherence, excellent directivity and monochromaticity, has attracted worldwide attention. In just 60 years, laser technology has developed rapidly. With the improvement of laser technology, industrial lasers have been widely used in traditional industries, and the level of traditional manufacturing has been continuously upgraded to intelligent manufacturing. Laser related products have gradually entered people's daily life. We are familiar with the applications of laser cutting, laser welding, laser marking, laser projection, laser printing, laser medical treatment, etc.

So, in practical applications, how do we control the laser and point it accurately to the target area? This requires the use of energy transmission fiber and components. Generally speaking, energy transmitting optical fiber refers to the optical fiber that can realize laser energy transmission. It has high power transmission capability, good flexibility, high strength, low transmission loss and high damage threshold. The energy transfer components mainly refer to the devices matched with the energy transfer optical fiber, such as high power output head, cluster connector, etc. As the link between the light source and the material to be treated, the components of energy transmitting optical fibers are indispensable in the laser application process. It realizes the flexible transmission of energy and accurately introduces light energy into the area to be processed, which is an important part of precision machining.

Introduction to Energy Transfer Optical Fiber and Component Product Series

Depending on the application of energy transmission fiber, the selection of energy transmission fiber and component type is also different. The following focuses on the performance and index requirements of energy transfer components in common application scenarios such as industrial laser processing, laser projection, printing and medical beauty.

Energy transmitting optical fibers and components for industrial laser processing

In industrial laser processing, the light source with high energy density shines on the material to be processed through the energy transfer optical fiber jumper, and the temperature of the material rises rapidly after absorbing the light energy and melts or vaporizes. This requires that the energy transfer jumper must withstand a high optical damage threshold, so that it will not be burnt out during the high energy density optical transmission. In addition, the optical transmission efficiency should be high. On the one hand, high transmission efficiency can reduce transmission loss, maximize the application of optical energy, and on the other hand, reduce the thermal effect caused by loss. As the processing is a dynamic process, the energy transfer jumper will move with the movement of the processing equipment, which also puts forward certain requirements for the energy transfer jumper material, which should have good flexibility and wear resistance.

At present, industrial laser processing applications mainly include QBH output heads for high power and HP-SMA and D80 optical fiber connectors for medium and low power. According to power strength and use environment, industrial laser processing applications can be divided into two types: with water cooling and without water cooling. However, the products on the market mainly rely on imports, and there are problems such as high prices, untimely delivery, and inadequate after-sales service. After years of technical research and development, Changfei has the ability to customize the whole industry chain from preform to optical fiber to component in the field of special energy transmission optical fiber. The special optical fiber and component products provided by Changfei can better meet the application needs of customers, and guarantee delivery and after-sales services.

The energy transmission optical fiber adopts stainless steel protective armor tube, which has excellent characteristics such as good central clamping degree, stable transmission efficiency, and low temperature rise of the baking machine. These products use special cladding large core diameter energy optical fibers. By optimizing the fiber core and cladding diameter, and cooperating with the connection process of connectors and energy transmission cables, the end faces are precisely polished to achieve efficient coupling and high energy transmission of optical fibers.

Multi core bundled jumper for laser projection and laser printing

Different from the conventional single core energy transfer fiber module, the multi-core cluster energy transfer jumper for laser projection and printing has multi port output. The multi-core cluster energy transfer optical fiber jumper is made of a special plug core. At the same time, the optimized manufacturing process of the cluster end can effectively prevent the negative impact of the heat generated by the laser accumulation.

Holmium optical fiber jumper for medical use

Medical holmium optical fiber jumper is widely used in clinical medicine because of its special working wavelength. The operating wavelength of holmium laser is 2140nm. Within the absorption range of water, water absorbs a large amount of light energy, which can reduce the damage to surrounding tissues, and make the postoperative reaction light and wound healing fast. Holmium optical fiber jumper can be used in urology, ENT, dermatology, gynecological surgery, etc. The Holmium optical fiber jumper products of Changfei Company have passed the biological compatibility test, and are applicable to a wide wavelength range (532nm~2200nm). The use of pure silicon core and double cladding design has improved the laser transmission efficiency of 780nm~2140nm. In addition, different core diameter optical fibers can also be provided to meet various needs.
