	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!
