National defense information technology gave the news that China has independently developed a high-power pump coupler, which also means that China is at the world's leading level
in the manufacture and research and development of fiber lasers.
For a long time, one of the core components of fiber lasers in the high-power pump coupler is imported, and the main function of the pump coupler is to aggregate the pump optical coupling in multiple thin fibers to a thick fiber and output higher power pump light, which works like the root system of trees: many side roots transport and converge water in the soil to the main root and inject into the trunk, the stronger the water absorption and water transport capacity of the primary root and the side root, the more water the tree can get, so as to flourish.
In order to get rid of the dependence on imported core devices, CETC put forward the goal of fully localizing the core components in the "high-power fiber laser", and finally realized the localization of core components such as beam combiners and pump couplers in just half a year
.
It is reported that the pump coupling pump optical injection power independently developed by China exceeds 1200W, and the coupling efficiency is up to 97%, reaching the international advanced level
.
Fiber laser (Fiber Laser) refers to the use of rare earth elements doped glass fiber as the gain medium of the laser, fiber laser can be developed on the basis of fiber amplifier: under the action of pump light, high power density is easily formed in the fiber, resulting in the laser energy level of the laser working substance "particle number reversal", when the positive feedback loop (forming a resonant cavity) can be properly added to form a laser oscillation output
