Abstract： The stigmatic beam with orbital angular momentum is generated by transforming the Hermite-Gaussian beam of a diode-pumped Nd:YAG laser through a rotated cylindrical optical system. Behind the transformation optics the output beam has an intensity distribution of ring shape and a twist phase. The beam transformation is theoretically calculated and the result has been confirmed in the experiments.
