摘要

We show a variable pulselength laser to be extremely useful whenninvestigating the dynamics and parameters of optomechanicalnnonlinarities in optical materials. Pulselength variability allowsnobservation of the transient nonlinear behavior using nanosecond pulsesnand determination of the underlying physical mechanisms usingnsubnanosecond pulses. It also enables observation of the transitionnresponse between the two time regimes where intrinsic polarizabilitiesncompete with optomechanical effects. We examine the transient nonlinearnscattering properties of an optical power limiter, platinum ethynyl, andncompare it to carbon disulfide using degenerate four-wave mixing.nIntensity, polarization, and pulselength control allow us to measurenacoustic scattering and decay parameters, Χ(3)nmagnitudes, and the transient laser-induced grating behavior
