In dispersive media the bandwidths of generated sum- or difference-frequency pulses can be greatly enlarged by use of previously chirped generating waves. It is shown that this technique is even more advantageous for shorter pulses and at a higher dispersion regime of the crystal. Experimental examples are also discussed.
