If I shine a laser at a mirror, it would be reflected back. If I got a super powered laser, could I still reflect it back? Would it start burning through the mirror? I'm thinking it's a case of imperfect reflection. If there were such a thing as a perfect reflector, you could reflect any laser, regardless of power level. However, if your mirror is only 99% perfect, 1% of the energy will be absorbed, and start to heat up the material of the mirror. Then it would just be a matter of time until your mirror gets too hot, depending on the material and the power of the laser. Does this sound correct? And does anyone know what sort of limitations there are for reflecting lasers?
