Light beams with flat-topped profiles

Not Accessible

Your library or personal account may give you access

Abstract

A necessary condition for generating optical beams with a nearly uniform profile at a certain transverse plane is proposed. This proposal leads to the introduction of a set of light beams with flat-topped profiles. This set of beams can be expressed as a finite series of lowest-order Gaussian modes TEM00 with different parameters. The main features of this set of beams are investigated and compared with those predicted by existing models of flattened Gaussian beams.
