Abstract

We are fabricating fast, diffraction limited cylindrical microlenses for applications such as collimating the strongly divergent axis of a laser diode bar.¹ The lenses can be mounted in close proximity to the laser bars, leading to robust, convenient, and relatively inexpensive packages providing low-divergence laser light. The reduced divergence of the lasers with the microlenses in turn reduces the required speed for any following optical system.
