Abstract

To meet the needs of some physical experiments for high energy short pulse laser, TGC (tiled gratings compressor) technology and beams-combination technology are required. Progress of TGC and beams-combination at CAEP is introduced. On TGC technology, interference pattern and far field distribution is used to initially eliminate the tiling error, and displacement sensor is used as feedback to maintain the posture of the sub-gratings. As for beams-combination a preliminary method of feedback control in subsections is proposed and will be expected to be used in an integrated test-bed.
