# New infrared laser weapon made by the USA - How does it work? [closed]

I have seen this post:

New infrared laser weapon, the Laser Weapons System, could shoot down drones or disable ships: US Navy

You can watch the video as well. that exhibits a laser weapon which can burn a fighter aircraft.

I have two questions:

• How does it work?
• Is it possible to create a mirror which can reflect the laser beam back ? If so, why won't the mirror burn up as well?

are you thinking of burning up the source? –  anna v Apr 9 at 14:09
no but how a mirror can be stable where the air craft gets burn –  0x90 Apr 9 at 14:13
The protection could just be a polished coating all over. There will still be vulnerable parts, like wheels, windows and plastic parts that will burn though. –  anna v Apr 9 at 14:15
There is a flag suggesting that this is off-topic. I'm inclined to agree that "how does [complicated weapon system] work?" is pretty marginal: it's probably more about integration and systemization than about physics as such. However the secondary question about the mirror is a good one, and there may be good questions about the physical principle behind some parts of the technology. @0x90 if you could refocus the text on the mirror I would feel it should remain open. –  dmckee Apr 9 at 23:41

It works by heating the object. It is a large high power laser that emits in the infrared part of the spectrum.

I guess there is a load of electronics for aiming the thing at a moving target to keep the beam localised and speed up the process.

As mentioned in the article a reflective coating on the target could work very well to mitigate the heating effects.
