[sci.electronics] laser freaks?

hobbit@topaz.rutgers.edu (*Hobbit*) (12/04/88)

Are there enough laser enthusiasts out there to warrant creating another
group?  Like for discussing lightshow issues, CDRH variancing, power supply
design, optics, where to get cheap parts, etc?  Or am I only one of a very 
few people that spends any time on this sort of thing?

If you want to talk about it, start talking.  The rest of us will tell
you when the traffic has gotten voluminous enough and annoying enough
to justify a new group.  There is no need for a new group until there
are messages to go in it.

I am interested in laser shows an whatnot, but I am content to keep it in
this group. I do have Laser show question for anyone to answer. 
I worked on a laser show some time ago, and the only economical way I 
could come up with to make one was with two 8 inch bass speakers 
with control rods moving a mirror. Each speaker controlled one dimension,
one did X, and one did Y. Now, I see that someone (Fordham I think)
is selling a laser light show for $90.00. How are they able 
to package a laser and the controls into a cheap setup like this?
And, more important to me, How are they bending the beam? Are they 
using a mirror or Kerr cells or what?  I am burning up with curiosity
about this...,  any help is greatly appreciated!

At least you haqve one really enthusiastic laser fanatic here!!!
So letws talk about lasers, modulators, frequency doublers, colimators,
holography, lightshows, etc, etc, etc.
Actually, there is a lot to talk about

If that's the case. Let's start talkin'

I have a high power OEM HeNe (35mW) that I want to use in public. Anyone
knows what have to be done??. I know there is a jungle of safety rules.
What I know about is.

  delayed key-switch (min delay ???)
  built in power supply.
  mechanical shutter.
  on indicator.

What else??
