Multi-pulse laser-induced damage threshold (LIDT) was experimentally investigated up to ~106 pulses for Cu, Ag mirrors. The surface roughness and the hardness dependence on the LIDT were also examined. The LIDT of OFHC-Cu decreased with the pulse number and was 1.0 J/cm2 at 1.8 × 106 pulses. The expected LIDT of cutting Ag at 107 pulses was the highest; Ag mirror would be one of the best choices for ITER Thomson scattering system. For the roughness and hardness, material dependences of LIDT are discussed with experimental results.
