7. 5. High Harmonic Generation in Hollow Core Waveguides

   Master-uppsats, Lunds universitet/Atomfysik

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

   Sammanfattning : 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. LÄS MER
