Normalization of the Mathieu-Gauss optical beams [PDF]
, 2007 A series scheme is discussed for the determination of the normalization constants of the even and odd Mathieu-Gauss (MG) optical beams. We apply a suitable expansion in terms of Bessel-Gauss (BG) beams and also answer the question of how many BG beams ...

Phase-matchable nonlinear optical interactions in periodic thin films [PDF]
, 1972 A proposal for a new method of phase matching in nonlinear optical interactions is made. A periodic perturbation of the surface of a thin-film waveguide generates space harmonics with new propagation constants which can be phase matched.
