uhh... what is a 100 watt laser capable of?

Let's see...Cutting metal/glass when focused, lighting paper or wood from across the street probably....and probably a hell of a longass match lighting and balloon poping....stuff like that

I saw that before....also like their portable YAG gun.
I wonder how high would those score on the osama scale

why still there is nobody using lasers like guns ? i was wondering

Cause they're still not efficient enough.

They claim a 1.5mm beam with less than 1mRad divergence on the 20 Watt CO[sub]2[/sub] tube.Is that a typo? Can you really get such good beam specs with a CO[sub]2[/sub] laser? :-/ 20kV @ 15 amps , but still, would be cool to mount on a turet on your roof

That would be 15 ma. At 15 amps/20kv the thing would be sucking over 300,000 watts.

Sorry, my bad. 15ma it is ;D

the power supply delivers 100 watts. The LASER, however delivers mere 20W.

I wouldn't buy from someone who claims 10% efficiency is superb for a CO[sub]2[/sub] laser. Since when can 20W "easily cut ceramic"? Oh, and let's not forget that "beam size <1.5mm, divergence <1mr"... I call BS[sup]3[/sup]

I figured......CO[sub]2[/sub]s aren't quite cut out for super deadly laser ray guns

Maybe just to burn someone up close.....
They also promise a 500J pulse out of their protable YAG gun which suposably delivers 150 shots from AA batteries.....I assume you would need a whole crap load of AA batteries though...

+10 ;D

I built one of his YAG guns 25 years ago !! Big pulse and difficult to make >

I wish I had the funds to build one :'(

For this price range ? Yes its quite good, the average efficiency for a sealed CO2 laser is around 5 to 8%, so yes a 10% efficiency for this kind of laser and at this price range is quite good. You can have more efficiency with a different mixture of gases and with a flowing gas setup, but you wont find one for $400 ....
The beam size and divergence will depend on the optics used, typical values for sealed co2 laser are 1-7mm for beam diameters and 2-6mrads for divergence, so the figures they're stating might be a bit off, specially the divergence, but somewhat doable

For 400 bucks this is quite a good tube even if it 'only' outputs 20W

Schrecken_Licht · Mar 15, 2008

That is misleading by saying "100 watts" when they mean input power.....+ their "considerable distance" isn't considerable at all.....any further than about 15 feet or so you can barely get cardboard to smoke....however, at close ranges (and when focused) that laser can chew into pretty much anything but metal....or thermally hardened ceramic glass.

That one will cut fiberglass cloth easily, melt ordinary glass, burn wood, vaporize flesh (no I didn't get caught in the beam!) and bone and melt plastic. Not too bad for a very low powered CO2 unit. It's also cool that you can see the "guts" of the laser (w/o fear of being electrocuted like some vids you see of home-built CO2 lasers where one wrong move....

) while in operation and how it's put together.

Here are some vids of that laser in action:

BTW, I did not buy it from that company - I got it unused (so the seller said, and it didn't appear to have been used very much if at all) on Ebay for a few dollars less than the cost of the unbuilt kit.

I have bought from this company before, though i have heard a few things about them. I wouldnt buy a co2 tube when you are risking it being broken.

Hemlock_Mike · Mar 15, 2008

I have purchased 3 CO2 laser tubes from Ebay. Only one arrived as chips and was replaced no charge.

Cyparagon · Mar 15, 2008

How are those coming by the way, Mike?

I beg to differ: 40W tube for $330 shipped

100 watt laser for under 2000$
