Magnetic resonance of cesium atoms in the case of optical pumping by radiation from a single-mode injection laser

An investigation was made of the influence of single-mode radiation from an injection laser on the magnetic resonance signal as a function of the laser radiation frequency. It was found that the amplitude, phase, and rate of decay of the free precession signal depended on the tuning of the laser radiation frequency within the Doppler profile of the line representing the hyperfine levels of the ground state of cesium.
