We describe an empirical expression for the case when nonlinear refraction is accompanied by nonlinear absorption to seperately evaluate the nonlinear refraction and the nonlinear absorption by performing straightforward measurements with the aperture removed. The nonlinear optical response of Pd(po)(2) was determined by the linear decreasing irradiance-dependence. The nonlinear absorption orginates from the near reasonant two-photon absorption transition enhancement. The linear increasind dependencies of the optical linearities on the incident irradiance arise from the population-redistribution due to the near resonant two-photon absorption. [References: 8] 收起
