This paper considers the sources of instability of laser-emission characteristics including external (temperature, injection current, pressure, etc.) and the physically unavoidable radiation-modulation sources that determine the minimum spectral line width. The measurement of the emission linewidth of an isolated mode of an injection laser is discussed. Some experiments are examined for injection lasers of increased monochromaticity and stability of the frequency. The energy-level scheme of a cesium-133 atom is shown along with a luminescence line profile of cesium-133 vapor excited by a frequency-scanned GaAs injection laser. The author discusses the application of single-mode injection lasers for fiber-optics communication based on single-mode light pipes. An appreciable increase of the information capacity can be expected, the author notes, in holographic memory devices, by replacing the ordinary injection lasers by single-mode ones with narrow emission line. In a number of devices in which gas lasers are used because they are highly monochromatic, single-mode injection lasers can also be used.
