    "abstract": "Accurate knowledge of absorption coefficient of a sample is a prerequisite\nfor measuring the third order optical nonlinearity of materials, which could\nbecome a serious limitation for unknown samples. We introduce a new method,\nwhich measures both the absorption coefficient and the third order optical\nnonlinearity of materials with high sensitivity in a single experimental setup.\nWe use a dual-beam pump-probe experiment under different conditions to achieve\nthis goal. We also demonstrate a counterintuitive coupling of the\nnon-interacting probe-beam with the pump-beam in pump-probe z-scan experiment.",
