Abstract
We show how to decouple a coherent Gaussian beam having general astigm atism (to transform it into a beam having only simple astigmatism, or orthogonal symmetry) by using a single rotated thin cylindrical lens. The resulting coherent orthogonal Gaussian beam may be further transfo rmed into a stigmatic (rotationally symmetric) Gaussian beam by an ort hogonal telescopic magnifier. The initial beam parameters must be know n; we suggest a procedure for their measurement.
