| Abstract: | Based on Fraunhofer diffraction integration, we have developed a theory onfocusing characteristics and beam quality of aberrated beam of which the phase aberrationis assumed to be a Gaussian random variable. Both approximate and calculated resultshave been presented. It is applicable in designs of nigh power lasers. |
