Abstract
The development of the color seperating gratings(CSGs),used in the field of ICF,is introduced.The CSG's area is 80mm×80mm.The change of beam near field percentage modulation is tested when the CSG is put in the optics system on the XGⅡ laser facility.Experimental results show that no increase of beam near field percentage modulation is found when the CSG is put in the system under the low power density of 0.005GW/cm2.
