Paper Abstract

External self-focusing of picosecond laser radiation has been used to measure the non-linear refractive index, n2, in several liquids. Beams of Gaussian temporal and spatial profile incident on thin samples (sample thickness smaller than the confocal beam parameter) are observed to undergo considerable self-focusing by monitoring the beam profiles on a vidicon system. Near field beam distortion and transmitted on-axis irradiance are measured as a function of irradiance, pulsewidth and polarization state of the incident radiation, to determine the value of n2 and the relative contribution to n9 from the fast and slow nonlinearities. The liquids studied in detail are carbon disulphide and nitro-benzene.
