Theory of attosecond pulse generation
This chapter will discuss the theoretical aspects of producing attosecond pulses via the process of high harmonic generation driven by an intense infrared laser pulse. We will discuss the generation of attosecond pulses both at the single atom and at the macroscopic level, including a discussion of phase matching. Our goal is to broaden the understanding of attosecond pulse generation beyond the single atom level, where one thinks about the emission in terms of the laser-atom interaction alone, to include macroscopic aspects of this process. © Springer-Verlag Berlin Heidelberg 2013.
