Abstract
DURING a recent discourse at the Royal Institution1, I wished to illustrate the effect of Q switching on the peak intensity of light emitted by a pulsed ruby laser and also to demonstrate the occurrence of intensity dependent two quantum processes. This was achieved in a simple and striking manner by using the best known of all photochemical demonstrations, the hydrogen chlorine explosion.
