Aluminum foil reflects about 85% of visible light. Gold reflects 98% of visible light. Neither of these materials would be effective in protecting against a 100kW laser. That remaining 2% is 2kW of light energy directed at a small target. It’ll rapidly ablate the gold foil and then the target will begin to absorb the full power.

- chongli 5y agoThe goal of the laser is to destroy the electronic detonator inside the warhead. If the detonator is destroyed then the potential damage from the missile is reduced from catastrophic to manageable. With a 100 kW laser I think the whole process could happen in less than a second.
