I'd like to get some info CO2-lasers... I read the following on a BBS..
If anyone has a sequel on this, please email it to me..

               LASER WEAPONRY / PART 1 / LASER SIGHTS

                     by The Deceptor and Flip

  WELCOME!.....To part 1  of LASER WEAPONRY - to be  included in  each issue
  of ELEKTRIX. This first tutorial deals with building your own laser sights
  as seen in films such as 'THE TERMINATOR' and actually used by US military
  and UK M.O.D. for such  weapons as ANTI-TANK GUNS,  APRLs and other high-
  power military weapons. The type of sights mentioned here can be strapped
  onto the barrel/tube and provide perfect targetting - also phreaks people
  out if you walk down the street pointing the beam at people.

  NOTES:

  1) The laser used is a helium-neon one which emits a bright red beam.
  2) Pointing it in someone's eyes will probably blind them so be careful
     with where you point it - unless ofcourse you intend to do damage (?!)
  3) It can't burn skin or paper or anything - it's only really useful in
     this case as laser sights - although in future issues I others will
     explain how you can use it for Data Snooping.
  4) Total project cost is about 40 quid.

  WHAT YOU NEED:

  1) A Helium-Neon laser tube.
  2) A portable power supply (easily transformed into a backpack).

  A fairly decent tube can be obtained from BULL ELECTRICAL for about 25 quid

  J&N BULL ELECTRICAL
  250 PORTLAND ROAD
  HOVE, BRIGHTON
  SUSSEX BN3 5QT

  The specs. of the JN BULL tube are as follows:

  Maker: Philips (holland) - could buy cheaper direct I guess.
  makers ref.no: LHN-VLP/04
  type: Helium-Neon
  Size: approx 260mm x 40mm
  Striking voltage: 6-8KV
  Running voltage: 1.2-1.5KV
  Output: 1.6mW (not bad at ALL! - usual MAX is around 2mW!!!)
  Running current: 5mA
  Polarity: white lead = negative
            black lead = positive
  Estimated life: 5000 hours
  Warm-up time: 1 second
  Wave length .63+0.01um (62.8nm roughly - red part of spectrum)

  Although the light emitted is actually red you'll only see the actual beam
  if the air is misty or dusty...though the spot at the end of the beam is
  perfect - the invisible beam is an advantage though if you don't want to
  be detected.

  I've included that info in case you pickup the beam as surplus stock some-
  where without the info. The tube isn't too fragile either - I dropped mine
  from two foot  once - nothing.

  As you're going to need a power supply that's portable then you'll be hard
  pressed to find a company that does one....so here's the docs.

 I hope people understand those schematics - TXT files make life so hard!...

 If you can't understand something then contacts us at Palm Beach and we'll
 send u a photocopy of our own docs if you like (fax optional).

 Use:
 ~~~~
 Strap the tube (maybe put it in a protective casing too) to the barrel/tube
 and then FIRE AWAY!!!!

 If you point it at someones eyes or your own then you/they can say goodbye
 to them for good.


 Phun with your tube:
 ~~~~~~~~~~~~~~~~~~~~
 As well as being GR8 for sights you can use it for other things:

 ~ Shine it at a neighbours window while they're sleeping and the room will
   fill with a eerie red light!! haha - gr8....and this can be done from a
   few hundred feet with excellant results.....

 ~ Another good use is to point it just in front of someones feet while they
   are walking....The red dot on the ground will make them REAL paranoid!

 ~ Picking up conversations in buildings by bouncing the beam off a window
   and via modulation of the beam and conversion at the opposite end you can
   hear very high quality conversations without being seen or heard - this
   is a bit more tricky though....details in the next ELEKTRIX issue.

 ~ PLAIN TERROR! YERRRRR! PHUCK this is the bit I love.....walk down the road
   real casual or through a town centre....carrying your nice laser....aiming
   the beam at people as they go by....This really phreaks them out...best if
   you and a m8 piss about and make out he's gone blind. People will run fer
   their lives - you need to add a nice buzz noise to it - that really makes
   it seem quite an awesome device!

 That's it for this LASER WEAPONRY issue.....a great addition for any launcher
 ,tube, rifle, or just about any direct beam weapon......It could also be a
 fantastic sight for a carbon dioxide laser (needed since CO2 lasers are not
 at all visible - phun).....YUP! CO2 laser is in Part 2 of LASER WEAPONRY...
 fully portable and with over 200W output we are talking *** SERIOUS POWER ***
