Notes:
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 χ(3) could be observed. For 2 MW incident power, corresponding to an intensity of 15 MW/cm2, at a wavelength of 676 μm a power conversion efficiency of 10−3 was reached. © 1995 American Institute of Physics.
