[Laser] IR laser Array???

[John Schnurer]

	Dear Richard, and anyone who wants to work with IR Lasers,

	It is a VERY good idea to buy a low cost IR viewing system and-or
cheap night vision viewer.  This way you can see what is happening with
the beam and its general magnitude.
	Otherwise pretend you are going to work with a visible laser....
but your eyes are closed... See how this is?
