Abstract : Identifiers: Quantum electronics.A laser employing an rf-excited gas discharge in a mixture of helium and neon is being studied analytically and experimentally. Experiments utilizing new developments in the field of optical masers are described. These include the interaction of intense laser beams with atoms. The effects considered were optical multiple quantum transitions by excitation with ruby laser light and level shifts produced by intense light sources. The study of the interaction of intense coherent optical beams with materials has started. Preliminary experimental work with low-power and medium-power lasers is described. The production of half-frequency radiation from an intense laser beam in a non-linear medium has been predicted theoretically and experiments have been initiated to detect the effect. In some paramagnetic materials there is evidence that anisotropic exchange is a dominant relaxation mechanism. A phenomenological analysis, employing the Block equations, yields the result that when such a system is driven into the saturation regime, odd harmonics of the fundamental appear in the output.
