Application and developing trends of mechanical tiling technology in the laser fusion device

Inertial Confinement Fusion (ICF) is an effective method to alleviate the energy crisis . As the key segment in the construction process of laser fusion device, mechanical tiling technology has played an important role in the field of laser pulse compression and final optics assembly. For this reason, grating tiling and off-axis parabolic mirror tiling are discussed primarily in this paper. The primary principle of tiled-grating assembly design is elucidated briefly, the movement adjustment process of 1×3 type tiled-grating and the driving process of 5PTSP-PPS serial-parallel tiling mechanism are reviewed. By analyzing the adjustment method of primary mirror in E-ELT, ideas to realize tiling off-axis parabolic mirror are proposed. Finally, some suggestions for further study on mechanical tiling technology are commented.
