The authors present the results of modeling the temperature drift of the resonator path length of a laser gyroscope based on a ring helium-neon laser with circular polarization of radiation and a magneto-optical frequency bias based on the Zeeman effect using the MATLAB mathematical package. The algorithm developed and implemented in the MATLAB environment makes it possible to simulat... https://www.morehartandweinman.com/product-category/digital-piano/
