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 P1 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 (σex) and ground state absorption cross section (σg) are estimated and found to be 1.78 cm/GW, 8.59 × 10−18 and 1.99 × 10−21 cm2, respectively.
