Times Cited Count:4 Percentile:87.01(Optics)We designed and fabricated high damage-resistant AR coating using AlO/SiO layers. As a result of irradiation test using 500 ps pulses at 1 kHz, the damage threshold of the AR coating was estimated to be over 36 J/cm (average value). We also fabricated high reflection (HR) mirrors using AlO/SiO layers added on TaO/SiO layers and measured damage threshold of them for 7 ns, 500 ps, and 1 ps pulses.
