Efficient generation of isolated attosecond pulse with CEP-unstabilized multicycle infrared double optical gating

Abstract

We proposed and theoretically demonstrated an optimized gating scheme, which we called infrared double optical gating (IRDOG), to create isolated attosecond pulses (IAPs) with a multicycle laser pulse. Our simulation shows that IAP can be generated by using a pulse up to 60 fs and carrier-envelop phase stabilization is not required. © Springer-Verlag Berlin Heidelberg 2012.
