Abstract
Methods will be described for achromatizing a previously described highly efficient refractive laser beam reshaper which allow a propagating, collimated, diffraction limited flat-top laser beam to be generated over a 200 nm spectral interval. Although the beam reshaper utilizes two aspheric lenses, the achromatizers detailed in this paper use only conventional spherical refracting elements. This allows a practical and cost effective path to upgrade such a beam reshaper to broad wavelength operation.
