Damage threshold and absorptivity measurements on dielectric coatings for high power excimer lasers are presented in this paper. The experimental techniques applied are in accordance with respective ISO standards. In particular, we give a detailed description of a newly developed UV laser calorimeter which allows high precision determination of absorptivities for transmissive and reflective UV optical components. The measured dependence of the damage data on the laser pulse length and shape as well as the correlation between damage thresholds and absorptivities observed for high reflection coatings indicate that the thermal model for laser induced breakdown is still valid for 248 nm radiation in the nanosecond pulse length regime.
