ABSTRACT:
A monolithic optical device formed from a GRIN rod having a centered aperture at an exit end thereof is bonded to a laser exit face to couple laser radiation through a spatial aperture without the alignment sensitivity characteristic of the prior art by the sequence of fabrication and alignment steps, whereby the output beam from the spatial filter is essentially subject only to vignetting as a result of misalignment of the optic with respect to the laser beam, rather than to the distorted wavefront characteristic of such misalignment in the prior art.
