Divergence reshaping array
Abstract:
A divergence reshaping apparatus for laser diodes having a fast axis and a slow axis includes a fast axis collimator element having positive optical power in the fast axis and no optical power in the slow axis. A slow axis magnifier element has no optical power in the fast axis and positive optical power in the slow axis. An objective element has positive optical power in the fast axis and no optical power in the slow axis. A slow axis collimator element has negative optical power in the fast axis and positive optical power in the slow axis. Every element is optically aligned down an optical axis, and wherein a beam traveling through every element is collimated, compressed and shifted in the fast axis and expanded and collimated in the slow axis.
