LGN–303, LGN–303-1 LASERS
He–Ne gas lasers of continuous operation mode with emission at two orthogonally polarized single-frequency components. Are intended to be used as a coherent emission sources in interferometry, optical location, fiber communication, technological and laboratory facilities. Operation modes: I — orthogonally polarized single- frequency components are divided spatially (LGN-303), II — superposition of orthogonally polarized single-frequency components (LGN-303-1), III — one high-frequency component with vertical vector of polarization on the laser output (LGN-303). Frequency stabilization is performed by means of thermal control of the resonator length.
