  • Abstract
    An oscillation at the wavelength 4946 A in cadmium sulfide crystal is produced by two-photon excitation by ruby laser radiation. A two-photon absorption coefficient is measured at the wavelength 6943 A. The two-photon absorption coefficient is proportional to the light beam intensity and is equal to 1.0 cm-1at 50 W/cm2. The excitation lifetime in excited state is 10-9to 10-11seconds. It is proved that the oscillation in cadmium sulfide is due to the coupled excitations.
