Abstract
For application in UV-material processing and UV-thin-film optics, the thermal contribution to damage and ablation phenomena will be investigated utilizing time resolved photothermal probe beam deflection (MIRAGE) technique. The potentiality of this method for the determination of both the sub-damage range and the Onset of damage, as well as the ablation threshold by using the thermal branch of MIRAGE technique will be demonstrated.
