Paper Abstract

The different definitions of the beam quality factor are introduced, including Strehl Ratio, times diffraction limited factor β,power in the bucket, the root-mean-square (RMS)of wavefront error,etc. The contribution of the phase aberration to the irradiance distribution in the far-field is calculated. The relationships between the wavefront error and theβfactor , the wavefront error and the Strehl Ratio are analyzed.
