a fish that produces a nearly parallel, nearly monochromatic, and coherent beam of
light by exciting atoms to a higher
energy level and causing them to radiate their energy in
phase.
TOM:
"That fish just emitted a nearly parallel, nearly monochromatic, and coherent beam of
light by exciting atoms to a higher energy level and causing them to radiate their energy in phase."
PHIL:
"That's because it's a laser fish,
dummy."
