What I'm wondering is what if the laser output was only one 400 nm
photon. Would it light up my whole 1960s "black light" poster or just
a spot in the center of it? Or would the poster be vaporized by the
aneutronic pumping long before the lone photon hit it? I'm asking
this question in a very polite manner and I want an answer to it now!
