Z-scan Divfotonu absorbcija Fizika Nelineārā optika Kerra efekts

description

Darba gaitā tika pētīti organiskā savienojuma DMABI dažādu atvasinājumu divfotonu absorbcijas (DFA) un Kerra efekti, lai iegūtu informāciju, kā dažādas funkcionālās grupas ietekmē iepriekš minētos nelineāri optiskos (NLO) efektus. Plašāka informācija par saistībām starp molekulu uzbūvi un to NLO efektiem ļaus veidot atbilstošākus organiskos materiālus dažādām iekārtām optiskā starojuma jaudas kontrolēšanai, optisko datu ierakstīšanai un apstrādei. Šādu iekārtu izveide ir būtiska optisko datoru veidošanai. Materiālu pētīšanai tika izveidota eksperimentālā iekārta pēc “z-scan” metodes principiem. Eksperimentālie mērījumi tika veikti izmantojot lāzerus ar nanoskeunžu un pikosekunžu gariem impulsiem, lai pārbaudītu dažādus NLO efektu mehānismus, kas var izraisīt gaismas laušanas koeficienta un absorbcijas izmaiņas.
