6. 5. High Harmonic Generation in Hollow Core Waveguides

   University essay from Lunds universitet/Atomfysik

   Author : Aaron Von Conta; [2012]
   Keywords : Phase-matching; High Harmonic Generation; HHG; Strong Field Approximation; SFA; Atomic Dipole Phase; Hollow Core Waveguides; Mode Propagation; Quantum Optics; Physics and Astronomy;

   Abstract : The main goal of this thesis is to initiate a set of experiments on high-order harmonic generation (HHG) in hollow core waveguides and to verify a higher conversion efficiency of HHG in waveguides compared to classical HHG schemes. High harmonics are in this context electromagnetic waves generated by focusing laser light into a dilute noble gas. READ MORE
