Abstract :
A configuration—two transmission volume phase gratings superposed is presented, where the gratings´ vectors are parallel to each other. Its diffraction efficiency is up to 90% for ultra-short laser pulse. The configuration enhances the gratings´ performance for ultra-short laser pulse, such as its spatial filtering, beam deflecting, and so on.
