Abstract
The distance of the virtual source of the laser output beam from the mirror is calculated by treating the radiation far field for which an analytical representation is given. The results show that for typical narrow-stripe gain-guided lasers the astigmatism is much stronger than would be obtained with a cylindrical phase-front approximation.
