Peculiarities of refractive index dispersion of TGS crystals
Based on solving the Kramers-Kronig integral equation, binding the spectrum of refractive index n(ω) of dielectric experimentally measured in the range of transparency (ω) and its spectrum of absorption index k(ω′) in the fundamental range (ω′), the dispersion analysis of these parameters has bee...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Based on solving the Kramers-Kronig integral equation, binding the spectrum of refractive index n(ω) of dielectric experimentally measured in the
range of transparency (ω) and its spectrum of absorption index k(ω′) in the
fundamental range (ω′), the dispersion analysis of these parameters has
been proposed. The elaborated method has been applied to the triglycine
sulphate crystal, in which the display of valence electrons interaction has
been established, and the temperature dependence of the characteristic
parameter of this interaction has been studied in the region including the
ferroelectric phase transition at Tc = 49 ◦C. |
