The high-power pump coupler is one of the core components in the fiber laser, and it is also one of the key components that China Electronics Technology has achieved in its “high-power fiber laser†and the key device's domestic self-controllability. As the name implies, the main function of the pump coupler is to couple the pump light in multiple fine fibers to a coarse fiber and output a higher power pump light. Its working principle is similar to that of a tree root: many lateral roots will be the soil The water in the medium is transported and collected to the main root and then injected into the trunk. The stronger the water absorption and the water supply capacity of the main root and the lateral root, the more water the tree can obtain, and thus the foliage is flourishing.
Both the "primary" and "lateral" roots of the high-power pump coupler allow high-power pump light to pass through, and high-concentrated pump power is injected into the downstream laser system to increase the power level of the fiber laser. Each fiber laser has one or more pump couplers or even multiple pump couplers. These large and small, various “roots†gather energy levels from all sides into the “major artery†of fibers. The ultimate high-power, high-brightness laser output. High-power lasers range from hundreds of watts to tens of thousands of watts. They are like cutting iron and razor-sharp razor blades. They are capable of laser cutting, laser welding and laser drilling in the automotive, marine and aerospace industries. In high-power laser weapons, they have demonstrated their talents, contributed to the high-end manufacturing industry, and escorted the defense industry.
At present, the high-end pump couplers in domestic "high-power fiber lasers" are almost monopolized by imported products. Not only are there risks of embargoes and supply interruptions, but also the prices of imported products are high, the procurement cycle is long, the specifications are limited, and the technical performance indicators are also It is difficult to meet the demand for equipment development.
In order to get rid of dependence on imported core devices, China Electronics Corporation proposed the goal of fully realizing the localization of core devices in "high-power fiber lasers." China Electronics 23 is responsible for the task of developing high-power pump couplers.
Within a short period of half a year, China Electronics completed nearly 20 special studies, conquering the technical problems of high efficiency coupling of pump light, high-power damage prevention, high-power fiber optic device heat sink packaging and universal design, and completed project development on time. The goal is to realize the localization of core components such as beam combiner and pump coupler, and the self-developed pump coupler pump light injection power exceeds 1200W, and the coupling efficiency reaches 97%, reaching the international advanced level.

Process
The sheet is processed in the following steps: decoil the raw material, feed with a fixed length via the servo motor, shearing it with various shearing tools into sheets of various types according to the drawing and then piling them on the stacking table via the conveying mechanism and the arranging mechanism.
Functional features:
1. This device can complete automatic production of various sheets for laminated, Full tapered seam cores.
2. Shearing power: imported electrical servo control technology is adopted, so the device is featured by high speed, low noise and long life.
3. Feeding power: adopt high torque AC synchronous servo motor, so has characteristics such as rapid response, high positioning and accuracy, low noise, low braking thermal loss and long life.
4. Track positioning: the centralized positioning is achieved by dragging the linear tracks of the ball screw with a servo motor. So the positioning is rapid, accurate and convenient and the track width can be memorized automatically.
5. Movement control: advanced PCC control and ethernet powerlink communication technology is adopted, reducing greatly wiring and imporving the reliability, stability and real time of the system remote control and trouble diagnosis can be achieved via the above control and technology, shortening the maintenance time and reducing the cost to the largest extent.
6. Arrangement mode: the backward pushing arrangement mde is adopted and long sheets can be arranged orderly with low vibration, reducing the orientational permeance of the processing process on silicon steel sheets to the largest extent.
7. Life guarantee: standard components of the device are imported quality ones. High accuracy of processing and assembly of basic components extents the service life of the device to the largest extent.
8. This device is a high techmechanical, optical and electrical integrated product with multiple patented technologies, it represents high manufacture level of domestic transverse shear lines and can substitute imported products, saving much outsourcing fund. Some models have automatic cut in cut become column functions.
