Influence of magnetic spin resonance in optically transparent magnets on the character of laser radiation

The influence of electron spin resonance on laser radiation from a crystal, one of whose end-faces has been cut at the Brewster angle, is examined. It is shown that modulation of the intensity and polarization of the generated light should hold for definite, critical values of the Faraday rotation angles. A change in the structure of the laser frequency modes also hence occurs. The critical values of the angles of rotation can be attained by altering the direction and magnitude of the external magnetizing field.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 35–39, April, 1973.
