Abstract
A hologram element receives a first and second laser beams at a first angle relative to one another. The hologram element emits the laser beams at a second angle relative to one another. The second angle is less than the first angle. The result is that laser beams from widely divergent laser sources may be directed into the same optical channel. Closely spaced beams are thereby provided for multiple beam optical data storage systems.
