Optical arrangement for improving focussability of radiation from laser diodes has optically surface structured element consisting of mutually inclined surfaces on input and output sides

摘要

The arrangement has an optically surface structured element consisting of mutually inclined surfaces on its input and output sides with which part of the radiation is displaced so as to produce an improvement in focussability in general in both spatial directions. The slow-axis of the radiation is collimated as well as the fast-axis.
