| 中文摘要 | multi-layer dielectric (mld) gratings for pulse compressors in high-energy laser systems should provide high diffraction efficiency as well as high laser induced damage thresholds (lidt). nonuniform optical near-field distribution is one of the important factors to limit their damage resistant capabilities. electric field distributions in the gratings and multi-layer film region are analyzed by using fourier modal method. optimization of peak electric field in the gratings ridge is performed with a merit function, including both diffraction efficiency and electric field enhancement when the top layer material is hfo2 and sio2, respectively. a set of optimized gratings parameters is obtained for each structure, which reduce the peak electric field within the gratings ridge to being respective 1.39 and 1.84 times the value of incident light respectively. finally, we also discuss the effects of gratings refractive index, gratings sidewall angle and incident angle on peak electric field in the gratings ridge.
