Abstract: A laser damage facilities,which has mm size spot and operates in TEM00 mode, were achieved.In order to know the reasons of laser damage,the laser energy density was controlled near the damage threshold of the oxide thin films.According to the examined near threshold damage morphology,the damage mechanisms of the optical coatings can be divided into two types.One was caused by melting of the coating materials,another by exploding,induced with the inner stress of the film.The plasma generated was an important reason to expand the damage area.
