Abstract
According to embodiments, scanned beam source may include a first beam shaping optical element aligned to receive a composite beam of light carrying a plurality of wavelength components and a second beam shaping optical element aligned to receive the composite beam of light from the first beam shaping optical element and configured to modify the first plurality of wavelength components of the composite beam to a plurality of dimensions proportional to wavelength. The first beam shaping optic may be, for example, a top-hat converter. The second beam-shaping optic may be, for example, a polarization-sensitive clipping aperture, a wavelength-dependent clipping aperture, and/or an achromatic corrector.
