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.

We designed and fabricated high resistant AR and HR coatings using AlO layer for Yb:YAG tin-disk amplifier. The damage threshold fluences for 520 ps pulse (AR, HR) and 1.2 ps pulse (HR only) were measured by uncompressed and compressed pulses, respectively, from the regenerative amplifier in QUADRA-T. As results, the damage threshold fluence of the AR coating of AlO/SiO multilayer was 75 J/cm for 520 ps pulse. This is satisfied out target value 40 J/cm to use in the amplifiers. For the HR coating, the highest damage threshold fluences, 2.4 J/cm for 1.2 ps pulse and 123.6 J/cm for 520 ps pulse, respectively, were obtained by manipulating AlO/SiO layer thickness to set a point of the maximum electric field in the SiO layer.
