Abstract:

A new nonlinear optical(NLO) organic material, 1-(pyrene-1-yl)- 3-(4-dimethyl aminophenyl)acrylic ketone(PMAK), was synthesized and characterized with 1H NMR, IR, MS and elemental analysis. Meanwhile, the three-order nonlinear optical property of PMAK was tested by the Nd:YAG powder laser technology and the relevant parameters were determined. Nanosecond results are as follows:the refractive index n2=-3.5×10-17 m2/W, the absorption coefficient β=7.0×10-10 m/W, the polarization rate χ(3)=2.54×10-11 esu, the molecular hyperpolarizability γ=3.44×10-30 esu. Picosecond results are as follows:n2=-2.8×10-18 m2/W, β=8.3×10-11 m/W, χ(3)=2.49×10-12 esu, γ=3.33×10-31 esu.
