Hello people,
What object if any would be able to absorb all of the laser's energy in the form of heat?
I was thinking a black body would actually do this, but when I shine a laser beam at a black surface, the dot is much dimmer than if I were to shine the same beam on a white surface.
If in theory any object would be able to absorb all of that energy, would you not see a dot hitting the object at all?
Would it have no identifiable ending point and look similar to the end of the beam when lasing at night for example?
For some reason, I always had the impression that most black object only absorb a very small percentage of all the beam's energy. Am I right for thinking that?
Thanks!
