摘要: We report on the correlation between laser damage resistance, optical and physical properties of Sc2O3/SiO2 mixture coatings. Several sets samples with ten different ratios have been prepared by ion-beam sputtering. The atomic compositions thin films are quantified employing x-ray photoelectron spectroscopy depth profiles. Laser-induced thresholds determined single subpicosecond pulses (500 fs) at 1030 nm. Furthermore, Son1 multishot measurements realized in ultraviolet wavelength range (355 nm) pulse durations 5 ns. In addition, influence two substrate polishing qualities radiation resistance composite is discussed.
