High resistant multilayer coatings for thin-disk laser amplifier

We designed and fabricated high resistant AR and HR coatings using Al$$_{2}$$O$$_{3}$$ 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 Al$$_{2}$$O$$_{3}$$/SiO$$_{2}$$ multilayer was 75 J/cm$$^{2}$$ for 520 ps pulse. This is satisfied out target value 40 J/cm$$^{2}$$ to use in the amplifiers. For the HR coating, the highest damage threshold fluences, 2.4 J/cm$$^{2}$$ for 1.2 ps pulse and 123.6 J/cm$$^{2}$$ for 520 ps pulse, respectively, were obtained by manipulating Al$$_{2}$$O$$_{3}$$/SiO$$_{2}$$ layer thickness to set a point of the maximum electric field in the SiO$$_{2}$$ layer.
