    seeing how this will be for display only, you can simply use a weak positive lens to help reduce the divergence, you will need to have a few positive lenses (w/ar coating) to experiment with, to see what works for you,(Focal length wise that is). if you want to make a fancier set up you can make a Newtonian telescope (a negative and positive lens), chances are you want the lens up close to the lasers output, so be careful about sending bad reflections back into the laser's head, to reduce these reflections don’t use the flat of the lens towards the laser head , or at least angle lens slightly to kick the reflections away from the window!

    Yes they are, I was lucky to pick one up before Ben bought out the rest of the supply from that seller.

    Laser (the acronym derived from Light Amplification by Stimulated Emissions of Radiation) is a spectacular manifestation of this process. It is a source which emits a kind of light of unrivaled purity and intensity not found in any of the previously known sources of radiation. - Lasers & Non-Linear Optics, B.B. Laud.
