Abstract

Abstract : A new organic nonlinear optical material 3-(2-chloro-5-(trifluoromethyl)phenyl)-1-(3, 4-dimethoxyphenyl)prop-2-en-1-one(3-CPDP) has been crystallized from CCl4 . 3-CPDP crystallises in triclinic system with P 1 space group. The crystal is optically transparent throughout the visible region with an absorption cut-off wavelength at 442 nm and possesses a stable phase before the melting point temperature (154 °C). The 3-CPDP molecule exhibits a minimum nonlinear transmittance at focus for 532 nm laser wavelength. The nonlinear absorption coefficient ( β ), excited state absorption cross section ( σ ex ) and ground state absorption cross section ( σ g ) are estimated and found to be 1.78 cm/GW, 8.59 × 10 −18 and 1.99 × 10 −21 cm 2, respectively.
