The basic theory of quasi-optical Gaussian beam propagation and beam transformation by
simple optical elements is summarized, and coupling to and between Gaussian beams is …

For a physicist, and more generally for a scientist, one of the pleasures in everyday life is to
detect exemplifying manifestations and avatars of the topic he is working on. Why do small …

In the search for higher resolution, modern day imaging systems frequently employ objective
lenses with a high numerical aperture. Propagation of light through such lenses introduces a …

In order to investigate ponderomotive force in the relativistic regime, the interaction of
ultraintense laser pulses with free electrons in vacuum is studied both theoretically and …

The Gaussian beam is the simplest case of laser beams actually appearing in practical
optical systems. There also exist some other derived parameters, such as the Rayleigh …

Abstract The discovery of Lax, Louisell, and Knight (LLK)[Phys. Rev. 9, 378 (1974)] that
electromagnetic beams in vacuum do have a longitudinal component can be proved …

Hermite–Gaussian and Laguerre–Gaussian beams with complex arguments of the type
introduced by Siegman [J. Opt. Soc. Am. 63, 1093 (1973)] are shown to arise naturally in …

The analysis of many systems in optical communications and metrology utilizing Gaussian
beams, such as free-space propagation from single-mode fibers, point diffraction …

Light beams extending beyond the paraxial region are investigated by the correction
scheme of Lax et al.[Phys. Rev. A11, 1365 (1975)] All higher-order corrections for the …

Longitudinal electromagnetic fields generally become comparable with the usually dominant
transverse components in strongly focused, non-paraxial beams. For paraxial optical vortex …
