Caption: Both pictures show a bright emerald green point of light from a single plasmon laser emanating from the optical setup used by UC Berkeley researchers. These semiconductor lasers -- the world's smallest -- are extremely efficient, so the small amount of scattered light is clearly visible, even in ambient room lighting. Camera saturation of the bright laser light gives the impression of a larger spot.
