Abstract

The nonlinear optical properties of diphenylacetylene and bis(4-biphenyl) acetylene have been investigated using the Z-scan technique. In these experiments the solid materials were heated above their melting points into the isotropic liquid state using a temperature controlled hot stage. Using this method, the nonlinear optical properties of materials with low solubility or where the solvent may have a significant contibution to the observed nonlinearity can be measured. Nonlinear absorption and refraction have been measured to be 1.4 cm/GW at 532 nm which gives a two-photon absorption cross-section (sigma) ₂ equals (17 +/- 6) X 10^-50 cm⁴s/photon-molecule. The nonlinear absorption coefficient of molten refraction for both of these materials has also been investigtaed. Molten diphenylacetylene has a nonlinear refractive index n₂ equals 3.9 X 10^-12 esu. Surprisingly, the bis(4-biphenyl)acetylene appears to have a very small nonlinear refractive index. The optical limiting behavior of molten bis(4-biphenyl) acetylene has also been studied.
