THIS- if you want a laser reflector for some hypothetical scenario;
Electroplate some mirror-polished silver onto a big ass heatsink bulk metal. Aluminum foil by itself isn't going to do shit for any high-powered attack; as soon as it reaches a critical temperature the surface will get rough on a molecular level, decreasing the reflectivity 100 fold and burning a hole in itself.

This is part of why some lasers are pulsed: the average power is not too high, but the instantaneous power is high enough to cause the surface of the material to ablate anyway. At which point your reflectivity goes to crap.
