How does one go about setting up a lens for negative divergence? The reasoning in my head says you just need a convex lens mounted at the right distance from the LD... I know it cant possibly be this simple though...
Negative divergence? What do you mean by that one? You mean getting the beam to converge to a focus? If you have a collimated beam, you just move the lens a little further from the source, and it will bring it to a focus.
wow it really is as simple as I thought...... so what was so special about WL's pulsar having a negative divergence then? I thought it must have took osme huge engineering marvel to create it or soemthing... what's the big deal?
