Generation of nearly nondiffracting Bessel beams with a Fabry-Perot interferometer

摘要

A new concept for generating zero-order Bessel beams was studied theoretically. The spatial intensity distribution was calculated numerically using a wave optics model. Approximate analytical expressions were derived to describe the radial intensity distribution in planes perpendicular to the optical axis of an imaging lens. # 1997 Optical Society of America [S0740-3232(97)00311-6]
