Abstract
Different beam shaping techniques to obtain the flat-top focus in one-dimension have been compared. It's shown that the smallest flat-top focus can be achieved with no loss by changing the polarization of the incident beam in a spatially inhomogeneous pattern. This spatially variant polarization manipulation adds a new degree of freedom in beam shaping and predicts better and more efficient results than conventional methods.
