Abstract

The third harmonic generation of far-infrared (FIR) laser radiation in n-doped silicon was measured with full temporal resolution of the power fluctuations during the FIR laser pulse. Thus, the intensity dependence of the nonlinear coefficient Chi(3) could be observed. For 2 MW incident power, corresponding to an intensity of 15 MW/cm2, at a wavelength of 676 micron, a power conversion efficiency of 1.0 E-3 was reached.
