Title: Seeded attosecond-pulse generation in structured media: A road for attosecond optics

Abstract

We present an approach for controlling attosecond pulses just like one controls femtosecond pulses nowadays. Using an adequate medium constituted of aligned and pre-dissociated molecules associated with a ''seed'' attosecond pulse and a control ir field, we propose a scheme for generating secondary attosecond pulses with a high degree of control of their characteristics. By solving the time-dependent Schroedinger equation for a model pre-dissociated molecule (H{sub 2}{sup +}) irradiated by the control ir field and seed xuv pulse, we demonstrate that one can generate such well-controlled secondary attosecond pulses by achieving frequency tuning and up-shifting and control on the chirp of the secondary pulses, which can even be significantly shorter than the seed. We also show that their characteristics can be accurately predicted with a simple classical approach.
