its not that hard to understand you fucking idiots
[QUOTE=confinedUser;46688057]
except its not, it's still about lasers, just explaining the fact that on a much smaller scale the basic concept can be replicated easily.
[/QUOTE]
what, the concept of pointing more than one laser at something? thats literally the [I]only[/I] similarity bettween the two
the lasing medium is completely different, the wavelength of operation is completely different, the power, [I]everything[/I] is different, they may as well be apples and oranges

[QUOTE=confinedUser;46687986]
seriously a regular 1 mW laser pointer bought at the store operates, at 5 C - 35 C, [B]a fiber laser at 1mW runs at 750 C[/B][/QUOTE]
for what, like a fucking femtosecond? you cant compare the power output of a pulsed laser vs a continuous wave laser

I still think CIWS looks cooler though

Cooler, but notoriously unreliable and difficult to maintain. Hell ours was almost always fucking broke for the last year I was there. Had some of the best CWIS FCs you could ask for, they'd work their asses off doing maintenance, tearing down the gun etc. Couldn't keep it working mechanically for more than a few weeks before something else would break. Some of the proudest motherfuckers I know.
It looks like it piggybacks off of the MK 15's Director and air search radars though.
[QUOTE=confinedUser;46687863]that's cool although you could do this at home aswell, just grab enough red (or green) laser pointers cluster them together and make a focal point for them and there you have it. Although i'm sure at some point the mirror would melt not really to sure how to get passed that issue unless you have something that reflects the laser 100% without storing a percentage of the energy that is being produced.[/QUOTE]
Pretty sure you cant put out a kilowatt of power from a cluster of laser pointers, regardless this is essentially a large laser pointer if I remember correctly, meaning its one big diode
will a mirror deflect it?
When are we going to build giant nuclear death robots?
Could this be affected by refraction through air and such? I would imagine it would affect the beam quite a lot as it is operated on the ocean.

If it's like the Airborne Laser System, it has a system to counteract refraction.
I wouldn't be surprised if body armor manufacturers start factoring in reflection and heat dissipation over the next few decades.
[QUOTE=mastfire;46688448]will a mirror deflect it?[/QUOTE]
No. It might reduce the energy marginally, though I don't know how reflective mirrors are to the infrared spectrum.

Yeah, it definitely can't be easy with all those moving parts
Will probably be a while before it can take on ASMs or fast movers, if ever (which I'm okay with because gatlings are rad af)
[QUOTE=mastfire;46688448]will a mirror deflect it?[/QUOTE]
some of it yeah, mirrors absorb a good chunk of light. In order to deflect a lot of a laser's energy they use a dielectric mirror which deflects 99.9%, and timebomb a laser pointer can be either continous or pulse so yes i can compare them because nowhere did i ever specifically mention pulse. Obviously you don't know laser pointers too well otherwise you would of known that by now. and the only difference between a diode laser and fibre is
Highly collimated - the beam is close to straight
A single frequency / colour
Coherent / in phase - all the waves are going up and down at the same time
those make it unique but still share the same damn physics as any other laser
they should put huge speakers on it that play generic laser sounds every time it fires :v:
I'm guessing this is mostly going to be useful as point defense against missiles and such.
[QUOTE=StrawberryClock;46688846]I'm guessing this is mostly going to be useful as point defense against missiles and such.[/QUOTE]
it can be used against aircraft aswell, it's immensely powerful.

[QUOTE]Firing a laser from the surface of the Persian Gulf is challenging because heat, humidity, dust and salt water can reduce its power.
The Navy spent about $40 million over the past seven years developing LaWS, which actually consists of six commercial welding lasers lashed together and aimed at the same point. [B]It has proven effective at ranges of up to about a mile[/B].[/QUOTE]
Considering that planes can engage targets hundreds of kilometers away, the only thing getting close enough to be in range of that laser are anti-ship missiles and such.

your right, sorry about that i had a brief moment and had a brainfart about it scattering the farther it travels. still cool non the less.
If it there was dust in the air would you be able to see the beam?
A laser weapon? The future is finally coming!
[QUOTE=Limpid;46688080]I actually wonder if you would feel anything being hit by such a large laser, would it just turn you into a cloud of ash?[/QUOTE]
Actually the laser is so powerful that it generates an explosion on hit, it doesn't slowly raise the temperature until you catch fire as you might be thinking.
Same reason why a mirror would do shit against the laser, the laser would just blow the mirrors away.
Someone posted a video, imagine the target is a person.
[QUOTE=Lick;46689198]If it there was dust in the air would you be able to see the beam?[/QUOTE]
Its wavelength is out of the visible light spectrum, so no.

My favorite part about that is that it looks like he's using a god damn x-box controller
I don't know whats worse: Being shoot a missile and looking at the object who is going to obliterate you advance and being unable to do anything to defend yourself or knowing that there is somewhere a invisible and unstoppable laser that could kill in a glimpse.

well i managed to find a nice article that explain it, check it out [url]http://www.rp-photonics.com/dispersion_compensation.html[/url] this explains dispersion of said laser, it's rather interesting

well if you get hit by the laser your instantly dead pretty much so you probably wouldn't even have to time to react :v:
If a remember correctly lasers this powerful simply vaporize shit on target and the explosion is just the cloud of vaporized... person/vehicle expanding rapidly in a psuedoexplosion.

Although the video doesn't show that I think. It looks like the navy was just aiming at munitions aboard the drone ship. This is precisely how it would be used in that scenerio too. Just fire the laser at whatever munitions you see and watch them ignite. 100% accuracy allows perfect targetting of stuff like that.

If they can compact the system to fit on a truck, imagine the uses as a minesweeper.
ok it is pretty awesome that we now have giant laser guns, but isn't it a little wasteful to spend millions on a giant weapon that will probably never be used against a real enemy?
unless of course aliens/machines
but in the latter case we're just arming our enemies
