        A thin ruby crystal is illuminated by two successive intense short pulses of coherent light, t seconds apart, obtained from a ruby-laser source. As expected, the crystal will transmit the two pulses t seconds apart. But then one observes a curious additional feature: a third light pulse emerges spontaneously from the crystal about t seconds following the second pulse, and still relatively intense.
