Paper Abstract

In this paper a commercial photothermal instrument is used to study the radiation effects on weakly absorptive optical thin film coatings induced by high repetitive laser pulses. Through in-situ measuring of the coatings’ absorption under irradiation of high repetitive laser pulses, the dynamic information of laser-material-interaction process is obtained, which is very useful for understanding and analyzing of laser damage mechanism of the coatings. In addition, absorption defects on the coatings are clearly determined through the photothermal imaging instrument.
