Abstract
A new method to determine the M-2 number in a single shot measurement is proposed and examples are given. The M-2 is calculated using a Four ier transform of the spatial phase- and amplitude-distribution in the near field. The measurements are done with a radial shear interferomet er. The method is easily applicable to a wide variety of lasers (IR-UV ) from CW to sub-picosecond pulsed operation: (C) 1998 Elsevier Scienc e B.V. All rights reserved.
