摘要
采用相位闪耀光栅原理设计出用于ＩＣＦ驱动器中能离轴分离基频、二倍频、三倍频激光的色分离相位光栅，理论上三倍频零级衍射效率达到１００％，同时，对该相位光栅进行了实际制作和实验测量，测出了基频光和二倍频光的分离角以及光栅的零级衍射效率。
With the use of the theory of blazed phase gratings,the color separation phase grating used for ICF drivers is designed,which can off-axis separate the fundamental,2nd and 3rd harmonic waves.Theoretically,its diffraction efficiency for 0'th order at the 3rd harmonic wave is 100%.Experimentally,a color separation grating is made.Both its separation angles (at the 1st and 2nd harmonic waves) and its diffraction efficiencies for 0'th order are measured,and some significant results are presented.
