| Abstract | |
We investigated the contribution of molecular orientation nonlinearity to the nonlinear ellipse rotation (NER) effect. There is an enhancement of 2.25 when this process is compared to pure electronic third-order effects. NER measurements were performed with picosecond laser pulses in SF6 glass and CS2 that respectively present mostly electronic and orientational nonlinearities. A Z-scan was also performed to probe the Kerr-lens signal. The enhancement effect can be understood by taking into account the tensor nature of the third-order susceptibility.
