At the National Research University Higher School of Economics (HSE University), a method has been created for calculating the optimal parameters of erbium-based fiber lasers. The development will increase the efficiency of high-speed communication systems and optical technologies. This was reported by the university's press service.
We have determined that the dependencies we calculated are universal for erbium lasers with significantly different core compositions of the active optical fiber, length, and resonator quality factor. The results will allow us to predict the generation parameters of erbium fiber lasers and optimize their operation for various tasks.
The researchers studied the generation of laser radiation in optical fiber containing erbium ions. The wavelength of the lasers is about 1.5 micrometers. This allows data to be transmitted over long distances with minimal loss and to create high-precision optical sensors.
Scientists have for the first time studied the effect of changing the concentration of erbium ions in the range from 0.03% to 0.3% on the laser's operating mode. The experiments made it possible to determine the optimal concentrations of ions of this rare-earth metal and to select a laser design in which it is possible to achieve compactness of the device while maintaining the continuous generation mode of infrared radiation.
It is expected that the research results will help fiber laser manufacturers in developing optimal emitter designs. This will improve the quality of high-speed communication systems and create more accurate optical sensors and detectors.
