Generation of highly phase-matched isolated attosecond pulses using multi-mJ, carrier-envelope phase stabilized, few-cycle laser pulses

Abstract

We generated highly phase-matched isolated attosecond pulses using multi-mJ, carrier-envelope phase stabilized, few-cycle laser pulses. Through the parametric amplification process of isolated attosecond pulses, only supercontinuum component was spectrally selected and by using a heterodyne interferometry using mixed gas, we found that the attochirp of the pulse is small. © Springer-Verlag Berlin Heidelberg 2012.
