Paper Abstract

An aberration factor, that is a general characteristic of the wavefront of the beam, is defined in order to quantify the aberrations of a beam, using the second moment method. This parameter can be easily calculated and measured from intensity measurements. Some examples are given and it is compared with the aberration variance, and related to the Strehl ratio.
