Today, various fields of science and technology use instruments, an important functional unit of which is a laser that emits in the region of 1.5 μm and has high stability of the generated wavelength. In this work, the possibility was studied of creating a radiation source that meets these requirements. The design was proposed of a solid-state laser based on Er3+:Yb3+ phosphate glass, the causes were investigated of frequency fluctuations in such a scheme, and experimental setups were proposed to determine the nature of the dependence of the radiation frequency fluctuations on component vibrations resonator.
