We investigate second-harmonic generation by an astigmatic partially coherent beam. An
explicit expression for the second-order correlation function of the second-harmonic field is …

The effect of degradation of the coherence of the pump beam by a random phase screen on
the conversion efficiency in the second-harmonic generation process is considered. It is …

The second-harmonic generation by a gaussian Schell-model source is discussed and
expressions are derived for the intensity distribution and the degree of coherence of the …

A numerical model is used to investigate the conversion efficiency of second-harmonic
generation with “nondiffracting” Bessel beams. We experimentally validate the model and …

Numerical studies of second-harmonic generation of beams with aberrations based on the
solution of three-dimensional propagation equations including diffraction and walk-off effects …

It is shown theoretically that second harmonic generation can be quasi-phase-matched by
using a pump beam consisting of a forward propagating field and a counterpropagating …

We experimentally demonstrate simultaneous phase and group velocity locking of
fundamental and generated second harmonic pulses in Lithium Niobate, under conditions of …

We show, for the first time to our knowledge, that the fundamental beam that participates in
the process of third-harmonic generation experiences an additional high-order nonlinear …
