Abstract

The nonlinear optical properties of doped semiconductors in the FIR-regime are due to the nonlinear motion of free electrons with respect to the electric field. This nonlinearity has been examined by frequency tripling experiments. Using fast Ge-hot-electron detectors it was possible to perform experiments with temporal resolution during the laser pulse. With an incident power of up to 1 MW at a wavelength of 676 micron, up to 2 kW power at the tripled frequency was obtained.
