Green Laser Pointers

  1. Jul 14, 2011 #1
    Hey guys, I'm wondering.. If I were to reflect a green laser pointer to the mirror, will the reflected laser be hot too? Or will I be heating the mirror?

    Depends on how perfectly reflecting the mirror is. But in any case, yes the reflected laser will be able to burn stuff (if it was able to in the first place), and just a small amount of energy of the laser will go to heating the mirror.
