Nonlinear optical spectroscopy measures the nonlinear optical response of a system to a set of intense laser pulses. The technique relies on the interaction between the electromagnetic field of the laser pulses and the material's nonlinear optical susceptibility. This interaction generates a nonlinear optical signal, which is detected and analyzed to extract information about the system's properties.
