Strategies to increase laser damage performance of Ta<sub>2</sub>O<sub>5</sub>/SiO<sub>2</sub> mirrors by modifications of the top layer design.
Applied Optics 2017 Februrary 2
Ta<sub>2</sub>O<sub>5</sub>/SiO<sub>2</sub> high reflection (HR) interference coatings for λ∼1 μm offer superior performance at high irradiance conditions. However, these coatings are not good candidates for high peak power conditions in comparison to HfO<sub>2</sub>/SiO<sub>2</sub> multilayer stacks. Here we show that the modification of the top layers design of a quarter wave Ta<sub>2</sub>O<sub>5</sub>/SiO<sub>2</sub> high reflector leads to 4-5 fold increase in the laser damage fluence compared to a quarter wave (Ta<sub>2</sub>O<sub>5</sub>/SiO<sub>2</sub>)<sup>15</sup> when tested at λ=1.03 μm using pulse durations of 0.19 and 4 ns and peak power densities of 43.5 and 216 GW/cm<sup>2</sup>. One of the designs achieved a laser damage threshold fluence of 174 J/cm<sup>2</sup> at 4 ns, which is 10% higher than that of a HfO<sub>2</sub>/SiO<sub>2</sub> quarter wave design.
