Has anyone played with an NEC NDL3200 laser diode?  I saw a very quick
demo of one yesterday, and today I talked with NEC.  Data sheets are
on their way, but I learned the following from NEC over the phone:

	Wavelength:		670 nanometers
	Output Power:		3 milliwatts
	Small-quantity price:	$260.00
	Availability:		Now

One of our local NEC distributors (Sterling in Woburn, MA) reports
having two in stock, but at $500.00 apiece.

The demo I saw was an impromptu one after a class at MIT.  One of the
other students pulled a small box out of his pocket.  A beam rather
reminiscent of that of a He-Ne laser was radiating from the box.  The
divergence did seem to be somewhat greater than that of a He-Ne.  I
will probably see this student again and be able to pump him for more
information before the data sheets arrive.
