Dynamic Kerr effect responses in the terahertz range [PDF]
The Journal of Chemical Physics, 2005 Dynamic Kerr effect measurements provide a simple realization of a nonlinear experiment. We propose a field-off experiment where an electric field of one or several sinusoidal cycles with frequency Ω is applied to a sample in thermal equilibrium. Afterwards, the evolution of the polarizability is measured.
