拼接型光栅对压缩器中子光栅的刻线密度不一致会降低压缩器的品质，补偿刻线密度差的影响对于提高输出脉冲的性能具有十分重要的意义.基于光线追迹的方法建立了理论模型，数值分析了刻线密度差所导致的出射光角度偏移及输出脉冲展宽程度.提出同时用水平角偏误差和纵向错位误差来补偿光栅刻线密度差影响的方案，给出不同刻线密度差时的理论光栅偏转角度和对应的平移距离以及该方案的补偿范围.利用空谱干涉测量方法，验证了该方案在一定范围内可校正出射光的角度偏转，较好地补偿二、三阶色散误差，且实验与理论结果较为符合.本研究可为拼接光栅压缩器的设计与调整提供指导.The grating groove density error (GGDE) will degrade the performance of the tiled-grating compressor, and the compensation for GGDE is of significance for improving the characteristics of the output pulses. With the ray-tracing method, analytical expressions considering GGDE are derived to predict the output beam drift and the output pulse broadening. According to the numerical results, we propose a compensation method to reduce the degradation of the tiled-grating compressor by applying angular tilt error and longitudinal piston error simultaneously. The tilt angle and the translation distance of the grating, as well as the allowable tolerance range of GGDE are obtained with this compensation method. By using the equiphase lines in the spatial-spectral interference patterns, the experimental results demonstrate that this compensation method can correct the angular drift of the output beams effectively, and compensate for the second-order and the third-order dispersion error well. Our investigation provides an efficient way to guide the adjustment of the tiled grating with GGDE.
