This paper deals with the study of characteristics of damage and damage onset of mirrors and substrates at 10.6 micrometers wavelength by means of photoacoustics using laser pulse irradiation with up to 10 pulses per on site. One group of the mirrors which have been investigated are commercially available polished uncoated Mo- and Cu- mirrors. A second set of mirrors consists of copper mirrors coated with NiCu, or Aumax, layer systems for enhanced reflectivity. NaCl and ZnSe substrates were selected as IR transparent materials. For measuring the photoacoustic waves generated by laser pulse irradiation, a piezoceramic detector is used. The amplified signal of the detector is sampled by a digital oscilloscope.
