MEASURING DEVICE AND MEASURING METHOD OF TERTIARY NONLINEAR TYPE OPTICAL CHARACTERISTIC

摘要

Device and method of measurement of the non linear characteristics of the emission of harmonics 3 of an isotropic phase 33: susceptibility, phase shift and dispersion. / p & & p & use is made of a beam which converges 1 in a prism 31 and diverges in a second prism 32 after having been focused 3 in the isotropic phase 33 which it travels over a distance that is variable as a function of / p. a.
