On the anniversary of the opening of Meykera the Institute conducted research similar phenomenon
(a) Measured and (b) theoretical angular dependence of the second harmonic spectral density
Fifty years ago, Maker with his colleagues observed for the first time the second harmonic intensity oscillations upon rotation of a nonlinear medium. The Maker oscillation phenomenon has become wide-spread in measuring nonlinear susceptibility of novel materials. By the anniversary of this discovery, the KIP’s researches have studied the analogous phenomenon implemented in a one-dimensional irregular nonlinear medium. Upon doubling the broadband laser radiation frequency, we observed the extraordinary angular behavior of the second harmonic spectral density and interpreted it as random Maker spectral oscillations (shown in the figure). The experiments are reported in Optics Letters.
