Dear colleagues,
this Wednesday we have a colloquium about
Generation of a Single-Cycle Optical Pulse, 23. Juni 2004
Stephen Harris Stanford University
"By using collinear Raman generation at maximum coherence, followed by liquid crystal spectral phase adjustment, we have recently attained a milestone result: the generation of a train of single-cycle optical pulses with a pulse width of 1.5 fs, a pulse spacing of 11 fs, and a peak power of about 1 MW. The talk describes the generation of these pulses, the use of a single cycle pulse for coherently controlled four wave mixing to the ultraviolet, and prospects for experiments with optical waveforms which have prescribed temporal shape."
