Design and demonstration of a tiled-grating frame

Development of a phased-array-grating compressor is a crucial issue for high-energy ultrashort pulse petawatt lasers. To achieve tiled array gratings and increase stability of tiled-grating frames, a new tiled grating frame is designed. In the tiled-grating frame, an integrated support structure is adopted to increase the natural frequency of the tiled-grating and the flexible hinges are used rather than the spring to increase the joint stiffness between the grating and the support frame. The experiment indicates that stability of the tiled-grating can be maintained for more than 1 h and the standard deviation of the tiling error is 35.7 nm, which satisfies the design requirement.
