Theoretical investigation and modeling of mid-infrared pulse generation in a GaAs crystal using 30 fs pulses from fiber-optical laser

The results of the THz radiation generation via interaction of 30 fs fiber-optical lasers pulses with the wavelengths of 1.98 and 1.55 μm in GaAs are presented. Numerical time-integration by the finite-difference method of nonlinear Maxwell-equation systems has been performed. The process of mid-inf...

Zusammenfassung:The results of the THz radiation generation via interaction of 30 fs fiber-optical lasers pulses with the wavelengths of 1.98 and 1.55 μm in GaAs are presented. Numerical time-integration by the finite-difference method of nonlinear Maxwell-equation systems has been performed. The process of mid-infrared pulse generation obtained from spectral filtration of a supercontinuum formed in the pump-pulse spectrum at the output of GaAs is studied.
