Fight fire with fire
That will teach those neds shining laserpointers in pilot's eyes!
US airliners'n'armaments colossus Boeing announced today that one of its prototype aerial laser cannon planes has fired its first energy bolts in ground testing. "First firing of the high-energy laser aboard the ATL aircraft shows that the program continues to make good progress," said Boeing blast-cannon biz boss Scott …
"People in the vicinity of an ATL strike might not realise what had happened until well after the event, if at all.". Well yes. Thats because their retinas will have been burnt out. Purposefully blinding the enemy is illegal. Though if they just happen to be looking at the target when it is hit, thats collateral.
You need really well polished surface reflectors in the arrangement of the inside of a cube.
And BIG ones at that.
TBH - even a few percent of that power getting back to the plane is going to seriously bad news, and a decent retroreflector ought to turn around practically all of the incident radiation - whether or not it hits the pilots eyes is pretty much a moot point
Cardinal of the Kremlin IIRC when a guy said about fitting ICBM's with mirrors and spinning them, and the response was that 'it's about as useful as a ballerina spinning in front of a shotgun. That energy has got to go somwhere". This is why the "Star Wars" mirrors, lasers, masers et al had serious cooling problems on the sending end...
As for reflecting it back to the aircraft, that would take some funky aiming to get it right... you may get fried a few times before getting it right, and that is only if the mirror does not get totaled by thermal shock beforehand.
Chrome is going to be back in fasion then.
Although this raises an interesting point - do you go ahead and chrome all your tanks / APC's / HummVees and risk the fact that you WILL be seen by standard weapons platforms, or do you go for the standard camo paint job and prey the pilot of the LaserPlane doesnt notice you?
Personally I'd like to see chrome battle tanks on the battle field, it'd just look cool.
According to Boeing's published tech specs, the laser produces a four-inch-wide infrared beam. Nobody on the ground would even see it, and it's unlikely that mirrors would help; gold is one of the few efficient infrared reflectors, and it's hard to imagine Third World countries plating all their gear in gold.
On a side issue you dont have to use a solid retro refractive surface, might be easier just to coat target in copper with a water jack over the top, High Specific heat capaity and all that and copper to dissipate heat over larger surface area.

No I'm sure the ET's have these things small enough to fit on hip holsters, or if you fancy some of the more obscure sci-fi, wrist mounted devices.
@Chris G: Yes! Because everyone knows that 'friendly friar' is more accurate!
also BTW polished copper is a good reflector of infrared, I imagine it could be used *behind* camo that is transparent to those frequencies ... OOPS, high $$$ tech once again 'foiled' by simple field engineering! Oh well, I guess its back to the plasma weapons.
1st, you can not see any wavelength of light traveling thru clean air, though I understand you have those visuals from science FICTION tv and films
while you might not be able to see it, infrared can certainly burn a retina .. but if you *observed* a good reflection of this laSer, it's likely your eyeballs would explode a nanosecond before your retinas were destroyed
as far as gold, maybe not third world, but wouldn't be too surprised if Putin were to gold plate a couple of those mobile Nuke's for next year's Red Square military gala, where he'll probably show off a bigger laSer than this, and gold plate that too ..
then US will start goldplating it's military stuff .. and we'll have a US-Russia Gold War until Sony develops it BlueRay Death LaSer .. then the Geneva convention will spend 10 years deciding which Death Ray format is to be used ..
.. and I'll probably be dead before I can afford a home use version <sigh>
my mind boggles, obviously
"Purposefully blinding the enemy is illegal." ooohhhh... naughty! It's the war crimes tribunal for you, Marine!
But slamming high-velocity depleted uranium into their craniums, blowing their limbs off with cluster bombs, burning them with phosphorus or melting them with microwave anti-personel rays ISN'T illegal, so, like, go for it!
The one they were showing off could burn through 8 centimeters of armor grade steel in less than 3 seconds from a range of .5 kilometers.
They then demonstrated with a block of acrylic. The beam sputtered out about half way through due to the dense smoke.
So, if you don't want something fried with a laser, cover it with plastic! Or just put it in a foggy area, lasers are useless in less than clear conditions!
(I'll be off then, to gitmo, for revealing state secrets!)
I get the distinct impression that the development of ideas for future weapons involves several cases of beer and watching the austin power movies. Next thing they will be proposing is to build a bigger version of this on the moon and calling it a "death star". Complete with an experimental Mini-me
Meh. It's a chemical laser. Those things can only go a few shots before the reactants are used up, and they create a load of really, really toxic waste products. I can certainly see the attraction of frying a truckload of Jihadis completely silently from 20 clicks away - if for nothing more than psychological reasons.
What we really need is a free electron laser capable of MW power output and low cycle time. That really would be a deathray worthy of the name.

This looks like a faked picture. The C-130 has landing gear that doesn't extend far enough from the airframe to land or take off with that dome hanging underneath. Perhaps the dome is retractable, but that's a lot of trouble when there's more apt and more stable platforms available.
There's no way they'd redesign the landing gear on a C130 to accomidate that. There's no reason to add complexity (and weight) to extremely heavy test gear by making it retractable. I wouldn't think that the low running cost of a C130 would be a deciding factor when you are developing a weapon such as this.
There's a slight odour of rodent in the air.
All of the mirror comments wont matter if they aren't kept clean, a spec of dust will begin to heat on the mirror surface and then burn it away, gold or not. As for peoples comments about it being kilowatt class and mirrors being useless at this power level, you can reflect gigawatt beams with no problem as long as you have the right wavelength (99.99% reflective) CLEAN mirrors.
And the bit that really bugs me: SILENT!!!!
you ever heard a laser melt something, or vap it entirely. Its not quiet.
I agree with the comments from David Giles, they sure do make some nasty waste. Infact if you totted up waste against usefullness these probably outweight a nuclear reactor.
Fire coz we all know burning stuff isn't silent
would be about the only thing that could reflect a LASER attack, and then they'd have to be optically perfect, which just doesn't happen in the real world. An ordinary mirror is still nothing more than a silver-plated bit of glass, and a LASER of the magnitude entertained here would simply burn off the plating in a few milliseconds. Plus the carrier material also absorbs some energy, so you'd get a smoking, expanding cloud of glass shrapnel partially plated with silver...
The acrylic idea mentioned by Captain DaFt should work for a few moments. The acrylic-protected object would probably get coated in another layer of partially-burnt plastics though.
I seem to remember in the old sci-fi role-playing game Traveller that you could buy either cheap ablative armour or expensive reflective armour to protect against lasers. Ablative armour would burn off after absorbing several shots, reflec lasted indefinitely.

If mirrors or optics don't work, what do we suppose they are using to aim the "frickin' laser beams" in the first place?
That aside, coating all potential targets in really shiny foil/mirrors/gold etc which reflect EMR ...even if this defends against lasers...kind of opens up the game to other targeting systems?
i.e. defeat the laser beam weapons, only to get blown to bits by the laser guided missile. Either way you're toast.
1 - You would not see the beam, as it is IR, but it can blind you. At that power, enough of the beam will be scattered by the air that is you are near it it will affect your vision, and blind you if you are near the target.
2 - Do not compare an IR laser to a electric fire. A 100W lightbulb is safe, a 100W laser is capable of burning through a brick wall. This is because laser light is very concentrated, it is a beam not an expanding sphere. It is also coherent.
3 - Mirrors do work on laser light, they are used in the laser after all. If you knew the frequency of the enemy laser, you could build a mirror capable of reflecting it. You could even build a roof mirror, similar to retro-reflective bike reflectors, to send it straight back to the aircraft. It would be very expensive though, a reasonable size, 99.9999% IR mirror would cost millions, and you would have to surround every target with them.
4- A 1-second killowatt IR laser pulse delivers 1 kilojoule to the target. 1 kilogram of RDX explosive on the sharp end of a cheapo missile delivers far, far more. Maybe this laser can burn out a cellphone mast, but dropping 250kg of bomb on it would also work, and form further away. Boeing have some work to do yet.
is very dangerous, so surely they'd just dump it on the enemy? Worst case scenario they're left with the waste. Best case scenario it wipes out hundreds of them pretty quickly.
It'd also mean that the carrier plane would be able to have a faster/longer return journey due to the lowered mass.
They should mount one of these on either a spherical death-star-alike blimp. With a bit of plywood over the thermal exhaust vent. That'd be awesome.

According to Boeing it *is* a C-130H.
The pictures on Boeings website also show the same C-130H but from different views, the laser dome slung underneath does look odd in relation to the ground clearance of these aircraft. So unless Boeing have photoshoped as portfolio of photos of this aircraft it is still confusing to how it hangs together.
my research did not establish if the device was retractable, or how this was delpoyed on its "ground based firing"? - the works firewall prevented to much poking around or maybe it was the black hats?
(yes, it is a modefied C-130H - it is not yet operational so wont have an AC-130X moniker, incidently there is more than one tye of AC-130 subtype. Boeing makes the *****ers so there shouldnt be any debate, even if it doesnt fit the percived wisdom of armchair military industrialists who are obviosuly moonlighting in IT for kicks)
...is all the fuss about, really?
I'm sure it's easier to use small, highly manouvreable projectiles (whether they're self-propelled or not) to take things like ICBM's and other missiles down. There are plenty of CIWS systems around, and I'm sure they'll keep evolving. http://en.wikipedia.org/wiki/Close-in_weapon_system
As for vehicles, what's wrong with good old boom-booms?
And I'm still waiting for my frickin' railgun, ffs! I bet it'd be much easier to get that working, and it would be so much more useful...
I wont bother explaining the laser acronym since several other people have posted it correctly, however I think that the term 'lazer' refers to a collimated beam of light produced from a lamp of some kind.
'lazer' light is not usually polarised in any way, nor is it made up of bands of frequencies ... it is simple white light that has been filtered and then passed through a system of mirrors/lenses to create a cheaper simulation of laser light for use in disco lights.

Mr T pities the fool who points this at him....
Mine's the coat with the A-team DVD in the pocket.
..more inane speculation on how yer average bathroom mirror would be an adequate defence.
To summarise the last article about this:
-Very few materials have good reflective properties in the IR spectrum
-Even fewer materials remain reflective when the polished surface heats up and boils.
-Dust and dirt negate relective properties
-Mirrors would make the target light themselves up nicely for <insert laser guided weapon of choice>
So we are left with the prohibitive expense of coating everything in gold and a little man with a tin of brasso on every street corner.
Now for high value assets, space shuttle-esqe ceramin foam might provide some protection...
Would a cloud of dust sufficiently diffuse this IR laser beam?
If so, in Persia it would seem the worst place to use a laser weapon.
Although, it would probably be pretty difficult to have some sort of dust-cloud generator device to protect critical infrastructure and object that could be used on-demand... since the "A"C-130 would still be kilometers away with no announcement of what they were going to target (let alone the fact that it looks like a normal AC-130, and not a futuristic space weapon thingy).

Advantages HSC of water means high energy to convert to gas,gas further disipates beam, water is cheap and can just be left running over retroreflective contouring on target or just submerge target in lake.
