    Abstract

    Pulsed photothermal deflection technique (pulsed-PDT) is employed to make in-situ investigations of laser-induced damage in optical coatings. Preliminary experimental 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 behavior and the cumulative effect.

    Keywords:

    laser damage, optical coating, in-situ investigation, photothermal deflection, pulse duration and wavelength effect, thermal property
