Dispersion of the nonlinear susceptibility of GaAs in the THz range

Dekorsy, T.; Helm, M.; Yakovlev, V. A.; Seidel, W.; Keilmann, F.

We investigate the nonlinear susceptibility of GaAs via SHG with a free-electron laser below the optical phonon resonance. The observation of a maximum and a zero-crossing allows the quantitative determination of higher-order lattice potentials.

Keywords: nonlinear optics; second harmonic generation; higher order lattice potential; free-electron laser; GaAs
