Applications of this type include anamorphic beam shaping and correcting the elliptical output of a laser . The Gaussian beam shaping system is composed of dual orthogonal aspheric cylindrical lenses. Elliptical beam shapes can be undesirable, as the spot size of the focused beam is larger than if the beam were circular, and as larger spot sizes have lower irradiances (power per area). An anamorphic shape for an image/beam can be achieved by using a pair of cylindrical lenses, making these an irreplaceable tool for the circularization of diode laser output beams.
