- rbarnes, on 07/10/2009, -4/+32"You know, I have one simple request. And that is to have sharks with frickin' laser beams attached to their heads! Now evidently my cycloptic colleague informs me that that cannot be done. Ah, would you remind me what I pay you people for, honestly? Throw me a bone here!"
- Lou3000, on 07/10/2009, -0/+18These guys have obviously not watched "Real Genius."
They need Lazlo. - BBarash, on 07/10/2009, -1/+19Real genius?

………………………..¯””^~~~~^” - PhillyMJS, on 07/10/2009, -2/+16I need 5 megwatts by May, Jerry.
- RagManX, on 07/10/2009, -0/+11"Needless to say, I was a little despondent about the melt down, in the midst of my preparations for hari kiri, it came to me. It is possible to synthesize excited bromide in an argon matrix. Yes, it's an excimer frozen in its excited state. "
- spiderman0505, on 07/10/2009, -2/+13I'm still waiting for them to make the Moonraker Laser ....
- DarthVato, on 07/10/2009, -1/+11And from now on, Kent, stop playing with yourself.
- Quaestor44, on 07/10/2009, -0/+9pew pew?
- Graeleight, on 07/10/2009, -0/+6It's like lasing a stick of dynamite!
- ilbbaicl, on 07/10/2009, -0/+6Stick to the Railgun.
- avianeddy, on 07/10/2009, -0/+5... too cold to hold.
- Wypie, on 07/10/2009, -0/+4...they're called the Ghostbusters and they're in control.
- PhilliesBlunt, on 07/10/2009, -0/+3You gotta know when to flush the coolant!! Adding more heat sinks might help too!
- inactive, on 07/10/2009, -0/+3What we really need to start looking at is phasers, or even disrupters.
- BigManOnCampus, on 07/10/2009, -0/+3You mean Chris.
- iconmaster, on 07/10/2009, -0/+3It worked pretty well against Devastator.
- BossKey, on 07/10/2009, -0/+2"Wanna see a demonstration of gravity?"
- Kapitaine, on 07/10/2009, -0/+2Why does a laser create so much heat??
- TwistyMcFister, on 07/10/2009, -0/+2Ghostbusters II reference:
http://www.youtube.com/watch?v=UhoU7lINYxk - Paranor01, on 07/10/2009, -1/+3perfect reference... especially since Mythbusters did a thing on it proving it wouldn't work dammit!
- Kapitaine, on 07/10/2009, -0/+2Technology rarely evolves without military use. Computers, microwave ovens, ballistics technology, space exploration, radar scanners, GPS, nuclear power all came from a military background. All have these have benefit you in very direct ways.
I'm not saying stuff doesn't happen without military interest, but it certainly gets a massive push. Commercial business is very short-sighted and can't see the domestic applications of such things.
The military are also now focusing on controlled sound waves. Imagine how that could benefit night clubs and bars in a domestic sense. No longer would you lose your hearing if you didn't want to from sound spillage. You'd only hear music at the dance floor at such high levels so that your're free to enjoy a normal social life without the hearing problems. I know my hearing is seriously damaged!! - ilovepopcorn, on 07/10/2009, -0/+2Just skip the lasers and go for heavy plasmas. Those sectoid bastards will never see it coming.
- endisnighe, on 07/10/2009, -0/+2I believe the rail-gun has been field implemented, its just that we don't hear about ***** for 30 years after implementation. F111 for example.
- inactive, on 07/10/2009, -0/+1Or a cure for cancer...
- zbeast, on 07/10/2009, -0/+1I always wonder what happens when you have dust on the output mirror.
being that most of these laser devices are going to be used in the middle east.
You know the place with ton's of sand and dust.. How do you keep from burning holes in your
own output mirror. do you have a team that does nothing but sit there with windex and roll of paper towels - Opiate, on 07/10/2009, -1/+2Cause proposing to spend colossal amounts of money elsewhere is going to fix our massive government and debt. The left and right crack me up, they don't care what it is .. as long as the state has total control over the populace and it's wealth.
- L4mb, on 07/10/2009, -1/+2Why not put them in space where the will be way easier to cool not to mention the awesome view.
- ducksgoquak, on 07/10/2009, -0/+1How are you going to create that heavy plasma near the missle? Maybe focus a big laser near it? Oh wait....
- B1665r, on 07/10/2009, -0/+1Well I have no idea what the military uses, but the front surface mirrors used in research grade telescopes reflect less than 100% of the light on them, the remainder of which they absorb. So even if they only absorb a tiny fraction of the light from a weaponized laser, i am sure they are still absorbing a significant amount of energy, and now your mirror is changing shape, and it starts to cascade from there.
- Nebarik, on 07/11/2009, -0/+1i love that dream!
- buckrogers1965, on 07/10/2009, -0/+1I don't think the problem is in the waste heat. The problem is in the laser only being 20% efficient at turning energy into laser beam. Boost the efficiency up to 50-70% and you can handle the waste heat easily.
And I don't see a way around the contamination on the lens or mirror issue, except by getting rid of the mirrors and lenses altogether.
I love all the real genius references, hilarious. - ducksgoquak, on 07/10/2009, -0/+1It's not the light from the laser that's causing the heat. In the article it says that it creates 4 Watts of heat waste for every 1 Watt of optical power out. That's only 20% efficiency which is actually really f-ing good for most lasers. A lot of lasers are pumped with things like xenon flash lamps which have a very broad frequency spectrum of which only small portions are absorbed to create the population inversion in the gain medium which makes the lasing possible. A lot of older lasers that i used were only ~2% efficient from plug to output optical power.
Hopefully that makes a bit of sense. - badfrog, on 07/10/2009, -0/+1Why am I the only one who has that dream?
- AWBoy666, on 07/10/2009, -1/+2I'm still confident we will figure it out so I can install a Tower of Nod in my front yard.
- Wosat, on 07/10/2009, -0/+1It’s your own fault, Knight. Didn’t anyone ever tell you to make sure your optics were clean?
- badfrog, on 07/10/2009, -0/+1That's hotter than the sun!
- benzzene, on 07/10/2009, -0/+1Contrary to popular belief, it's quite difficult to cool things in space. Look up the Herschel or Planck space telescopes.
You're right about the view though. - etx313, on 07/10/2009, -1/+1Too hot to handle, too cold to hold.
- flagger, on 07/11/2009, -1/+1George Lucas foresaw this problem, or some other star wars author. the proton cannons are lasers cooled with proton.
what they should do is stack hundreds of smaller lasers together with individual focusing - inactive, on 07/10/2009, -1/+1Oh shut up with that "government using tax dollars is always bad" crap already, it's getting old.
- kh99, on 07/10/2009, -9/+9-50 for telling us that it's a reference.
- bazzarr, on 07/10/2009, -0/+0Just put a giant magnifying glass on the end of a mechanical Wile E. Coyote type arm that pops out of the nose of an airplane. It worked for me as a child (on a smaller scale) with ants.
- bstepanian, on 07/10/2009, -1/+11.21 "jigowatts"!!!
- NotDennis, on 07/12/2009, -0/+0Maybe if we turned the money being funneled into the Deathstar to scholarships for low-wealth families we'd be a little farther from ignorance and gullibility and close to world peace.
- VikingBeatbox, on 07/10/2009, -0/+0Darn. My Bobby Brown/Ghostbuster's reference was taken.
- inactive, on 07/10/2009, -1/+1zap zap!
- golgotha, on 07/10/2009, -2/+2Was it a dream where you’re standing on a pyramid in sort of sun god robes with a thousand naked women screaming and throwing little pickles at you?
- Shinbone, on 07/10/2009, -1/+1Not sure I'm buying this story. My tinfoil hat is on the desk...wouldn't data like this be classified? I mean, "Our weapon systems development effort is falling behind." REALLY?
