Abstract
Optical devices achromatize the output from a highly efficient refractive laser beam reshaper, thereby allowing collimated, diffraction limited flat-top laser beams to be generated over a wide spectral interval, e.g., over 200 nm in the visible. While the beam reshaper may utilize refractive aspheric lenses, the achromatizers use cost effective spherical refractive elements.
