Apparatus and process for measuring non-linear order three optical characteristics in an isotropic phase

摘要

Apparatus and process for measuring optical, non-linear, harmonic emission characteristics of an isotropic phase: susceptibility coefficient, phase displacement and dispersion. Use is made of a beam converging in a first prism and diverging in a second prism after having been focused in the isotropic phase which it traverses over a distance variable as a function of the aperature angle alpha .
