A team of researchers from Germany has presented an ultrafast fiber laser system. It allows for producing an average power that is higher than 10× that of standard high-powered lasers. The fiber laser technology enables researchers to change both the speed and efficiency of industrial-scale materials processing.
It should be noted that the developed fiber laser has been already demonstrated at the OSA laser congress. The thing is that there is a combination of 12 laser beam amplifiers in the new laser system. Herewith, these lasers overcome current limitations provoked by laser beam light emission and waste heat.
Additionally, optical fibers used in fiber laser systems show “a laser beam geometry with a high surface-to-volume ratio. They effectively dissipate this heat. Therefore, current high-powered laser systems obtain an average power of 1 kW.” Nevertheless, the power increase leads to a decrease in laser beam quality because of the generated heat load, creating a limit.
Thus, the application of 12 amplifiers makes it possible to develop a laser system that can generate 10.4 kW average power. It is equal to 80 MHz repetition without any distortion or decline of laser beam quality. To be more precise, the fiber laser system has been already tested and test results demonstrate a small heating effect.
Moreover, the researchers claim that the use of more amplifier channels results in laser beam power scaling up to the 100-kW level. The fiber laser’s applications include such extreme fields as laser-driven particle acceleration and space debris removal in addition to material processing.
There are also other applications, for instance, high-speed scanning and ablation cooling. Herewith, the developed fiber laser system is not ideal and still needs improvement. Nowadays the researchers plan to discover new applications at the high-power level and the transfer of the fiber laser technology.
The team of researchers pays careful attention to multicore optical fibers that provide the potential to transmit further superior performance in simpler and compacted laser systems. If you are looking for a compact highly-efficient laser system, the Optromix company is ready to manufacture it.
