Optical nonlinearities of tetracarbonyl-chromium triphenyl phosphine complex

“…In the present paper, the nonlinear optical coefficients of our new complex -tetracarbonylchromium-triphenyl phosphine in dichloromethane compound listed in Table 1 were compared with previous results for molecules with the CW laser excitation. [33][34][35][36]…”

Study of Structure–Third-Order Susceptibility Relation of Indandione Derivatives

“…In recent years nonlinear optical (NLO) organic materials have attracted a great interest due to their potential for applications in optical limiting, optical data storage and optical processing. − In this regard, currently most of the effort is devoted toward finding organic NLO compounds with pronounced Kerr effect and two-photon absorption as well as efforts to define guidelines, which would allow to predict the third-order NLO efficiency of organic molecules. Both of these effects manifest themselves as material optical property dependence on the incident light intensity and have been extensively studied for several different organic materials. − These studies indicate that highly π-conjugated polymers have a great potential for current third-order NLO interests. Although the fact gives certain guidelines, additional qualitative criteria are necessary for performing substantiate material selection for specific all-optical devices.…”

Enhancement of third order nonlinear optical responses via alteration of the density of states of electrons: VS2–NiS2 hybrid nanostructure

“…This phase shift was computed by fitting of the CA/OA curve using the following equation: T ( z ) is the normalized transmittance for the CA/OA curve. Finally, the n 2 index was calculated via the following equation: 25 …”
