Efficient spectral broadening of mid-infrared pulses by use of a GaAs crystal has been demonstrated. The spectral bandwidths of the pulses at 5-μm wavelength increased from 540 nm to 2060 nm. The main advantages of this material are its large third-order nonlinearity and its transparency range (1 18...
