MAGNETOOPTICAL RESONANCES IN GENERATION SPECTRUM OF WIDE-BAND LASER WITH STRONGLY ABSORBING MEDIUM AND THEIR APPLICATION TO DETERMINATION OF GREAT OPTICAL DENSITIES

A wide-band laser, containing in the amplitude-anisotropic resonator a strongly absorbing atomic medium subjected to a longitudinal magnetic field, is considered. The resonances of the generation power of such a laser, arising within absorption dips, are shown to come about from the rotation of the polarization plane in the medium. Such resonances are proposed to be used for measuring great optical densities. In this way optical densities of potassium vapor at various temperatures have been determined at the frequencies of the resonant doublet.
