Divergence explains the ammount the beam will expand each meter, over a given distance. But what I was wondering was, how the divergence is effected after a reflection and whether using a device to reduce divergence (i.e beam expander) will increase brightness after a reflection.
In a few weeks I'll have the beam expander for the Spartan, so I was interested in finding out. Theoretically, the beam expander will make the beam brighter over a longer distance (not taking into account power loss after installation) than usual. Would reducing the divergence to .12mrad have any increasing effect off of reflections?
