Abstract
Four sets of mirror samples with multilayer system SiO2/Ta2O5 on silver metal layer were manufactured using modified coating technology of the metal layer. Both BK7 and fused silica substrate materials were used. Laser-induced-damage-threshold of mirrors was tested using a laser apparatus working at 1030 nm wavelength, 3 ps pulse length at 1 kHz repetition rate and in 105- on - 1 test mode. The measured damage thresholds values at 45 deg incidence and Ppolarization were compared for different substrate materials and different technology of the metal layer preparation. Additionally four sets of samples with silver layer covered by SiO2 protecting monolayer were manufactured and tested for the comparison.
