Paper Abstract

Output optical components on GaAs substrates devoted to the industrial CO2 lasers, delivering up to 1200 W c.w. power laser levels, were investigated as regards the aging behavior of the optical coatings. IR spectrometry and thermal runaway in passive regime offer information about the optical dielectric coatings evolution. A comparison between the two deposition methods: thermal evaporation in high vacuum and r.f. magnetron sputtering put into evidence better results for the last method as regards the aging behavior of specific dielectrics used in IR.
