Paraxial theory of sum-frequency generation by side-walk alignment and phase-matching in uniaxial crystals
non-linear optics, birefringence, sum-frequency generation
2011/9/5
A formalism in terms of Hertz potentials is presented describing sum-frequency generation in a uniaxial non-linear crystal. A scheme is proposed consisting in aligning the side-walk propagation of ext...
Influence of Phase Matching on the Cooper Minimum in Ar High Harmonic Spectra
the Cooper Minimum Harmonic Spectra
2010/11/16
We study the influence of phase matching on interference minima in high harmonic spectra. We concentrate on structures in atoms due to interference of different angular momentum channels during recom...
