摘要：
We report a broadband high-energy mirror for TW-class chirped-pulse amplification of approximate to 10-fs pulses. This mirror consists of broadband coatings and optimized high-damage-threshold coatings for decreasing the intensity on the broadband coatings. It is important to optimize the number of high-damage-threshold coatings so that high damage-threshold and relatively low dispersion are traded off against each other. The bandwidth of this mirror (Delta lambda approximate to 200 nm at lambda(0) approximate to 800 nm) is almost equivalent to that of a commercial broadband mirror, and the damage threshold of this mirror is almost equivalent to that of a commercial high-energy mirror. This mirror can withstand chirped pulse laser beam's with high fluence (> 1 J/cm(2)) and wide spectra (153 nm FWHM) in practice.
