Attosecond twin-pulse control by kinetic heterodyne mixing

Abstract

By using a two-color strong/weak-field combination of carrier-envelope- phase(CEP) stable laser fields interacting with an atom, we control the process of high-harmonic generation to create isolated and double attosecond pulses. Using this multi-parameter control approach, we can manipulate several properties of the attosecond double pulses independently, such as their intensity ratio and relative phase, being important prerequisites for interferometry and attosecond quantum control experiments. Both experiments and simulations will be presented. © Published under licence by IOP Publishing Ltd.
