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.

A Compact Broadband Terahertz Range Quarter-Wave Plate [PDF]
Journal of Infrared, Millimeter, and Terahertz Waves, 2020 We detail the design and characterization of a terahertz range achromatic quarter-wave plate based on a stack of aligned variable thickness birefringent sapphire discs. The disc thicknesses and relative rotations of the discs are determined through a basin-hopping Monte Carlo thermal annealing routine.
