1. 1. Quantum Optical Description of High-order Harmonic Generation

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isabel Moreno; [2024]
   Keywords : Physics and Astronomy;

   Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.
