Abstract
Femtosecond transient absorption pump-probe spectroscopy has been used to s tudy the third- and fifth-order nonlinear susceptibility of UV-grade fused silica. Theoretical simulations support the experimental evidence of interf erence between the third- and fifth-order contributions to the signal. Appr oximate values of the second-order nonlinear refractive index n(4) and of t he three-photon absorption coefficient gamma are obtained. (C) 2001 Optical Society of America.
