In dispersive media the bandwidths of generated sum- or difference-fre
quency pulses can be greatly enlarged by use of previously chirped gen
erating waves. It is shown that this technique is even more advantageo
us for shorter pulses and at a higher dispersion regime of the crystal
. Experimental examples are also discussed. (C) 1996 Optical Society o
