摘要：
Multi-layer dielectric gratings (MDG) have been more and more used in the chirped-pulse amplification (CPA) system because of its higher diffraction efficiencies and higher damage threshold, which is compared with metallic gratings. Design parameter of multi-layer dielectric and gratings are both given. Laser-induced damage threshold (LIDT) of MDG has been test by employing 1-on-1 methods. The result is 3.24J/cm(2) at 1064nm and 12ns pulselength (51.2(0) incidence). The mechanics of damage is also discussed in several ways.
