Abstract
In laser energy transfer, supergaussian reflectivity profiles seem to provide the best trade-off between output-pulse energy and beam quality. And in a different context, supergaussian, annular spatial filters are able to increase substantially focal depth, under incoherent illumination. Our aim here is twofold. First, we present an analytical formula that describes the wavefield, behind an aperture shaded with a supergaussian profile, of any continuous order. Second, we show that for certain GRIN fibers, some diffraction modes are supergaussian beams of continuous order.
