Study of Third-order Nonlinear Optical Properties of Basic Violet 3 Dye in Polar Protic and Aprotic Solvents

Abstract

The present work aims to study of third-order nonlinear optical (TONLO) behavior of basic violet 3 dye dissolved in polar protic and aprotic solvents, namely, ethanol, 1-propanol, acet0one and dimethyl sulfonate (DMSO), respectively. The polarity of the solvent used to have a substantial impact on the linear and TONLO properties of the dye sample. The dye exhibit self-defocusing nonlinearity due to thermally induced nonlinear refractive index and nonlinear absorption coefficient reveals the character of both saturable and reverse saturable absorption (RSA). The order of magnitude of nonlinear refractive index (n2) and nonlinear coefficient of absorption (β) of dye sample was determined to be 10 -7 cm 2 /W and 10 -3 cm/W, respectively. The real and imaginary factors of the TONLO susceptibility of basic violet 3 dye were measured to be the power of 10 -5 esu. The results are revealed that the possibility of utilizing the dye sample in various photonics and optoelectronics applications.

“…The absorption cross-section of excited state is greater than ground state which is the result of RSA. Furthermore, RSA of the sample elucidates by the five-level model and the detailed explanation is presented in our recently work [18]. The normalized transmittance from OA Z-scan technique is given by,…”

“…The solute-solvent interactions are commonly described in terms of non-specific (van der Waals) and specific (hydrogen bond) interaction [17]. Specific and non-specific interaction between solute and solvent is accountable for modification of molecular geometry, electronic structure, and dipole moment of the solute [18]. [19] is the sensitive experiment for determining the TNLO properties of the organic compound.…”
