Brightness of diffracted laser beams

Beam propagation factor (usually referred to as M2 factor) and brightness of high-order symmetrical Laguerre Gauss (LG) beams that diffract upon a hard-aperture are investigated. We demonstrate that a circular aperture is able to decrease the M2 factor of a high-order symmetrical LG beam and also to enhance its brightness although induced losses.
