Building a Laser Weapon |
Would It be possible to build a CO2 laser gun? Like a handgun or a
rifle? I plan on building one for a science project. It needs to be
able to burn a hole through metal at 2cm/sec. Would it also be able to
kill/maim people, b/c after I'm done at the science fair, I'm going to
patent it and license it to the LBPD and the military. Some help here?
Thanks!!!!

Other people have thought of developing lasers as weapons before you did,
and they had much bigger budgets and could answer these questions
themselves.
It's really very hard to beat the old-fashioned slugthrower. They're
small, lightweight, accurate, have a lot of penetration and stopping
power, they're rugged and reliable, cheap, and it's easy to carry more
ammunition than you're likely to need in any particular engagement.
They're versatile in that you can use ball, hollow point, armor piercing,
and other types of ammunition in the same weapon and rapidly change from
one to another. How would you expect a laser weapon to improve on that?
If you want high powered lasers, try the Thomas Register, the
industrialist's best friend.

THEY'RE trying to build a laser gun that'll blow up missles and tanks;
I just want to build something that can punch through a body and/or a
car door, even an engine block maybe. About the power source; would
using radium/a trizerium crystal fragment make the power supply small
enough to be placed in the grip?

"They" tried to build lots of different kinds of lasers, including
antipersonnel weapons. I'd read about a German group that produced a
weapon that would ionize twin paths through the air and run an electrical
current through it-- a wireless taser. The power supply was the size of a
refrigerator.

No. A radium-based power supply wouldn't produce energy as quickly as you
would need it.

Let's say the melting point of steel is around 1400 C degrees
above room temperature, the specific heat is around 0.1 cal/gm-C,
and the cross section area of your beam is 0.1 cm^2. The
density of steel is around 8 gm/cm^3.
So you want to melt (let's not worry about vaporizing for
now) 0.2 cm^3, of 1.6 gm of steel per second, which will
take 1400*1.6*0.1 = 224 cal/sec, or pretty close to 1000 J/sec
(a kilowatt). Given that metal is reflective and that you probably
DO need to vaporize some of the steel, you probably are
talking about at least several kW, unless I severely goofed
in my back-of-the-envelope calculation.
I'll leave it up to you to figure out if you can build a
5 kW laser in your garage.
Would it also be able to>
kill/maim people,
Last laser I worked with was 2 W. That was strong enough
to sting if I got my hand in front of it, like being pricked
with a pin. I'd say 5 kW would hurt.
Recommendation: don't kill or maim people at the
science fair. As impressive as it might be, I'm guessing
the judges won't award points for it and there might
even be a rule against killing and maiming at your
school.

5kW for 2 seconds.
Let's say at 12 V batter voltage 5000 / 12 = 416 A for 2 seconds.
or 416 / (60 / 2) = 13Ah battery with high current capacity.
Battery pack of *1* shot would be no problem.
Not counting efficiency laser.... There exists semiconductor laser
arrays that can do that much power, 1 kW is in the ballpark:

I'm not going to do that at the FAIR!!!! If I license it to the police,
it would need to kill/maim people, to be useful. Maybe I could get 15kw
from a small, in-case piece of radium, or a sliver of a trizerium
crystal. How would I design a small power supply for it, so it could
vaporize a thin, 5cm sheet of metal.

Didn't I read that weapons designed to blind people are illegal under
international law?

International Law? Never slowed GWB down before why should he change now?

obsolete
electric gun make the nuke obsolete.
Cops have guns and stun guns ..
they nead a front fender tow bar to hook a bumper with .
They nead a co2 blast to kill a cars engine with .

Dude, you are *way* old-school. There are *way* more fly weapons than a
stupid CO2 laser that would require a wonkin' power supply to lug
around and a permit to operate it.
You gotta viddy up on some *bitchin* weapons, byotcc.
