Why should anyone care about the power level, as opposed to the pulse energy?

people who have tattoos should care, for one. the ideal tattoo removal laser has really high instantaneous power but really short pulses. this way you get high power but low energy per pulse.

the tattoo ink breaks down better with higher power lasers because it breaks the bonds holding the ink molecules together. but by keeping the energy per pulse low, you're minimizing the tissue damage since tissue damage grows with the amount of energy absorbed by the skin. when you break up the ink molecules into smaller pieces then the immune system can flush away the bits into your lymph nodes. tattoo is gone!

+1 awesome.

for me the lesson here is that everybody is upset that he shot the drone with a gun. nobody's upset that he destroyed the drone. lesson learned, next time use a football or a golf club. those things are horribly unstable, and you tap one blade then boom.
