Abstract
The beam emitted by a laser diode chip is elliptical and astigmatic. Various methods have been proposed and applied to remove the astigmatism and to produce a circular Gaussian beam. In this paper we will further propose the use of the laser diode beam correction optics in an external cavity laser. The light produced by the external cavity laser is not only circular, Gaussian, and non-astigmatic, but its coherence length is also significantly enhanced.
