I have read that you can limit the divergence of a laser by sending it backwards through a telescope. I have not yet been able to do this with my telescope, but seem to have some success using less powerfull lenses. Would anyone be willing to help me conduct this expiriment. The problem I am having when using the telescope is I don't notice any beam comming out of the scope at all. What are some possibilities to what I could be doing wrong? When I use my other less powerfull 'telescopes' the beam stays very focused and small at a longer distance. From what I have read this technique only works with a NeHe laser, and I have one of those.
