A problem of a laser induced damage to dielectric coatings due to thermal explosion of the absorbing inclusions is investigated. It is shown that major parameters governing damage characteristics of the coatings are band gaps of coating and substrate materials. In particular, damage threshold dependences on a coating thickness and a position of the inclusion in the coating or on the coating-substrate interface are connected with an effect of this fundamental parameter. Experimental data are in qualitative agreement with theoretical predictions.
