We present a novel technique to align a tiled grating in all five relevant degrees of freedom utilized in the compressor of the high-power chirped-pulse amplification laser system Polaris at the Institute for Optics and Quantum Electronics, Jena, Germany. With this technique, alignment errors of the two gratings with respect to each other can be detected with an accuracy of 1   μrad for the rotational and 40   nm for the translational degrees of freedom. This is well sufficient to recompress 1030   nm pulses, which were stretched to 2 .2   ns before amplification, to their bandwith limit of 150   fs .
