Abstract

Pulsed phototherinal deflection technique (pulsed-PDT) is employed to make insitu investigations of laserinduced damage in optical coatings. Preliminary experiniental results show that the technique is capable of providing a lot of new information about not only the damage thresholds but also the damage processes of which of particular interest are the transient damage 1ehavior and the cumulative effect. key words: laser damage optical coating in-situ investigation photothermal deflection pulse duration and wavelength effect thermal property. 1 .
