Abstract
A graded-index microcylindrical lens functioning in combination with a laser diode beam to change the divergence of the fast axis on an incoming laser beam from one divergence to another, but not to collimate the beam. In one embodiment of the present invention, the graded-index microcylindrical lens changes the divergence of one axis of the laser beam to be substantially equal to the divergence of the slow axis.
