Abstract

Summary form only given.We have developed a new type of spectral interferometry with ultrafast temporal resolution based on the use of linearly chirped pulses. We have demonstrated that this single-shot technique can be used for measurements of the ionization dynamics of air produced by an intense short laser pulse. In principle, chirped pulse spectral interferometry could be used as a phase oscilloscope over a significant time span.
