Periodic Mo/Si multilayer mirrors with high peak reflectivity and broad reflection band for reflecting single attosecond pulse are designed, by optimizing the thickness ratio between the absorber layer and the bilayer. The reflective characteristics of periodic Mo/Si multilayer mirrors with different thickness ratio are analyzed and compared both in frequency domain and in time domain, for picking out optimized thickness ratio to achieve high-efficiency attosecond pulse reflection. According to our simulation, periodic quarter-wavelength Mo/Si multilayer mirrors with different layers all show better pulse reflection capability for incident Gaussian pulses than multilayers with other thickness ratio. When studying the spectral and the temporal responses of periodic multilayer mirrors, the transfer-matrix method and fast Fourier transform have been used in our simulation.
