Abstract
An investigation of the dynamics of catastrophic optical damage of a l aser diode facet showed that the characteristic energy-evolution time of optical damage was 40-80 ns under pulsed operating conditions. When the pulse duration was less than this characteristic time, the damage was governed by the critical energy of a pulse. An estimate of the th ickness of an overheated region gave less than 0.6 mu m.
