Abstract:
For the crystal and solution of 1-(3-thienyl)-3-(4-chlorophenyl)propene-1-one (TCPP), which is transparent over the whole visible region, the nonresonant third-order nonlinear dynamics is investigated by time-resolved degenerate four-wave mixing spectroscopy. The temporal nonlinear behaviors of both crystal and solution exhibit the instantaneous responses during 80 fs excitation at around 625 nm. The third-order nonlinear susceptibilities are determined to be |χ (3) b b b b | = 7.1 ×10 -13 esu for crystal and |χ (3)TC 1111 | = 7.1 ×10 -14 esu at 1 mol/l for solution. This suggests that the TCPP crystal has a large value of χ (3) /ατ= 2.4 ×10 3 esu·cm·s -1 under the assumption of the nonlinear response time τ= 30 fs (absorption coefficient α= 0.01 cm -1 ), which is a parameter important for ultrafast optical control materials. The obtained |χ (3) b b b b | value satisfies an already known relationship between the second- and third-order susceptibilities.
