Optical pulse compression to 3.4 fs in the monocycle region by feedback phase compensation
© 2003 Optical Society of America
We compensated for chirp of optical pulses with an over-one-octave bandwidth (495-1090 nm; center wave-length of 655.4 nm) produced by self-phase modulation in a single argon-filled hollow fiber and generated 3.4-fs, 1.56 optical-cycle pulses (500 nJ, 1-kHz repetition rate). This was achieved with a feedback system combined with only one 4-f phase compensator with a spatial light modulator and a significantly improved phase characterizer based on modified spectral phase interferometry for direct electric-field reconstruction. To the best of our knowledge, this is the shortest pulse in the visible-to-infrared region.
