Abstract

The slit scan method was implemented for registration of intensity profiles along the caustics of a laser beam. Inverse Radon transform of spatially normalized intensity profiles enable us direct computation of Wigner transform of real laser beam. The Rayleigh range, divergence angle, beam quality factor, global degree of coherence and some information of wavefront aberration can be determined in such a simple way. This procedure was applied for investigation of the aberrated laser beams generated by cw and pulsed diode pumped lasers.
