摘要：	Design and operation of a practical,accurate alignment diagnostic system is important for the grating tiling technology,which is supposed to be applied in a chirped-pulse amplification system to increase the output power.A diagnostic method is proposed and demonstrated for grating tiling.Provided that the wavelength and incident angle of the diagnostic beam are properly set,the far-field of the main laser beam and that of the diagnostic beam can vary in the same way with the tiling errors between the sub-aperture gratings.Therefore,rotational and translational errors can be controlled and compensated according to the far-field of the diagnostic beam.The real-time monitoring and alignment can be achieved without disturbing the main beam.
