Based on the Collins integral formula, an analytical propagation formula for the anomalous hollow beam passing through a paraxial ABCD optical system is derived and the propagation properties in free space are studied graphically.Abstract:
A theoretical model is proposed to approximately describe an anomalous hollow beam of elliptical symmetry with an elliptical solid core, which was observed in experiment recently [Phys. Rev. Lett.94, 134802 (2005)]. Expressions for the propagation factor and effective beam spot size for the anomalous hollow beam are derived. Based on the Collins integral formula, an analytical propagation formula for the anomalous hollow beam passing through a paraxial ABCD optical system is derived. The propagation properties in free space are studied graphically.read more

Study on propagation properties of a radially polarized partially coherent dark hollow beam through a high numerical aperture lens
TL;DR: In this paper, the authors investigated the tight focusing properties of radially polarized partially coherent dark hollow beam (DHB) through a high numerical aperture lens and showed that the optical intensity distribution in the focal region directly fluctuates due to small change in coherence length and high numerical angle of the focused DHB.

New developments in laser resonators
TL;DR: In this paper, the authors describe three recent developments not so much in laser resonators themselves as in the tools for analyzing and measuring the quality of laser beams and resonators, which include personal computer programs for analyzing laser beam and resonator properties, a new method for characterizing and measuring beam quality of a laser output beam, and a new "ray-pulse" method of analysis for describing beams.
