Frequency domain nonlinear optics: concept and applications

We use the concept of frequency domain nonlinear optics (FNO) to address various challenges related to the development of ultrafast laser sources. We find that FNO is a framework opening the door to novel nonlinear interaction schemes involving broadband, ultrashort pulses. Among the principal applications, we have achieved amplification of two-cycle pulses at 1800nm up to 2.5 TW and we have shown pulse shaping of deep-UV pulses at 207 nm.
