Interesting clip of a laser at work:

I hope the three laws of robotics are followed more closely than other laws we enact...

So the Chinese will have them deployed by the end of the year.

I always wonder how well this would work if the target was made of polished aluminium....
Maybe the people wearing the alufoil hats aren't that stupid :-P

These work by heating the object till something fails, even a polished aluminum surface will probably absorb 10% of the beam and loose it's surface finish quickly and then it is all over with.

AND if the object is a container under pressure or contains flammable/explosive material.

What about a mirror surface?

A laser reflector, use their own weapons against them.

Long long ago, I worked in a shop that had a ? 20 ? station Strippit Fabricenter.
It was the first around here to have a laser cutting station.

They had great success untill they tried to cut out brake-pads from sheet stock
with brass fragments all thru it.
It ended baddly, can't realy recall what all was damaged.

The Navy is interested in finding less expensive weaponry. Believe it or not, lasers, rail guns, etc are much cheaper to operate than conventional propellant based weapons. Sure, it won't work in every scenario, but the cost to fire a couple of high intensity IR beams is pretty negligible compared with large caliber weapons. That particular laser is one developed by Raytheon and has a range of a few miles. It was designed for taking out UAVs and explosives. As the video shows, the beam was used to detonate munitions/fuel carried by the enemy.

Others on the docket include Boeing's Free Electron Laser for taking down cruise missiles.
