Being a recent buyer of a 3mw helium-neon laser, I have a few questions
about the operation of the laser.
oWhy when viewing the lasers red 'dot' on a wall, does it appear to
have little 'dot's in the illuminated area? It looks kinda 3-d
(no flames about this being a 3-d world! :-) )
o What will happen if I go from 12v dc to 24v dc? What will happen to
the power in the beam?
o How can I defeat difraction on the beam over long distances?
o anyone have any interesting projects for something like this?
thanks!
