Quasiperiodic Raman Technique for Ultrashort Pulse Generation

Abstract
We report the experimental demonstration of a new Raman technique that produces 200 sidebands, ranging in wavelength from 3μm to 195 nm. By studying multiphoton ionization of nitric oxide (NO) molecules, we show mutual phase coherence among 15 visible sidebands covering 0.63 octaves of bandwidth.
