The research team of the IKBFU developed a fundamentally new method of manufacturing laser optics, which is based on the use of rare-earth metal ions of ytterbium and its oxide. The results of the work of scientists were recently published in the scientific journal Optics Communications.
Senior Researcher of the “Fabrika” Science and Technology Park, Ph.D. in Physics Anna Tsibulnikova told us: “During the experiments, it was found that the trivalent ytterbium ion, interacting with the same ion, glows red under infrared radiation. Previously, such a glow mechanism was observed only in systems containing several ions of various rare earth elements. For example, ytterbium, thulium, holmium, erbium. This means that it has become possible to significantly simplify and cheapen the production of laser optics. Rare earth metals are very expensive material, so using only ytterbium oxide in the production of laser media can provide significant savings”
