A gas-discharge He–Ne laser generating monochromatic radiation with λ = 1.52 μm for testing telecommunication systems

Abstract

The results of a detailed study of a gas-discharge He–Ne laser that generates monochromatic radiation with λ = 1.52 μm are presented. Such important laser parameters as the divergence of laser radiation, the laser power as a function of the temperature, the laser-power stability, and noise and spectral characteristics of radiation were measured. The attained parameters of laser radiation in the aggregate occurred to be virtually ideal for using the laser in tests of telecommunication systems. The possibility of laser microminiaturization is shown, which is of interest when using it under the conditions of a high level of electromagnetic noise.
