Abstract
Results of a detailed study of a gas-discharge He-Ne laser with a wavelength of 1.52 μm for telecommunications systems are reported. Some important parameters of the laser are measured, such as the laser beam divergence (M2), the laser power as a function of temperature, laser power stability, noise characteristics of laser radiation, etc. A possibility of laser microminiaturization is mentioned, which is of interest for its application under conditions of intense electromagnetic interference.
