摘要
The function of dispersion interferometer with the investigated medium between the two crystals as well as inside the laser resonator in the constant-constant approximation taking into account the changes of the interacting wave phases is analyzed. This approximation allows the effects of phase mismatch and losses in a medium on the course of a nonlinear process to be taken into account simultaneously. Intensity minima of the harmonic (as opposed to the constant-field approximation) in the constant-intensity approximation are shown to depend on dispersion of the refractive index of the medium under study, which makes it possible to determine dispersion of the refractive index of the substance under study directly and accurately. It is shown that the use of the nonlinear conditions of dispersion interferometer with the medium inside the laser resonator allows to increase the interferometer sensitivity.
