    "abstract": "Accurate knowledge of absorption coefficient of a sample is a prerequisite\nfor measuring the third order optical nonlinearity of materials, which can be a\nserious limitation for unknown samples. We introduce a method, which measures\nboth the absorption coefficient and the third order optical nonlinearity of\nmaterials with high sensitivity in a single experimental arrangement. We use a\ndual-beam pump-probe experiment and conventional single-beam z-scan under\ndifferent conditions to achieve this goal. We also demonstrate a\ncounterintuitive coupling of the non-interacting probe-beam with the pump-beam\nin pump-probe z-scan experiment.",
