Abstract

Investigations of the linear and nonlinear optical properties of a series of enyne oligomers in solution are carried out. Linear absorption spectra are compared to predictions of the free-electron model. Degenerate forward four-wave mixing is carried out at 1.064 μm with pulses of 50 ± 25 ps. Intensity dependences reveal a well-behaved third-order process. Measurements of χ⁽³⁾ as a function of concentration reveal contributions from both real and imaginary components which may not be accounted for by the free-electron model. Real components are found to be negative at longer chain lengths. Imaginary components are attributed to localised virtual transitions.
