Abstract
THE use of saturable absorbers such as aluminium phthalocyanine for the passive Q-switching of ruby lasers1 raises the question of the lifetime of the active molecule. We have measured the lifetime of that state of aluminium phthalocyanine which corresponds to absorption at or near 6943 Å. Similar data for magnesium phthalocyanine have been obtained, for comparison with literature values.
