Aspects of Attosecond Pulse Generation Through High-Harmonic Generation

Abstract

We systematically optimize the yield of XUV pulses at 93 2 eV with respect to experimentally adjustable parameters such as gas pressure, focal position of laser beam and interaction length by using few cycle laser pulses. We demonstrate carrier-envelope phase dependence of the optimized XUV spectrum, consistent with the formation of isolated attosecond pulses. We present the progress to- wards a newly developed attosecond beamline and describe its essential parts in detail. We perform initial experiments on photoelectrons detection. This work will contribute further for optimizing the setup for attosecond streaking experiments.
