首次在光参量啁啾脉冲放大激光器中证明了物像栅自拼接光栅压缩器的啁啾脉冲压缩和光束聚焦能力。在我们的演示中不再需要传统拼接光栅压缩器通常需要的用于拼接误差调整的探针激光器。利用压缩器中第二光栅的两倍有效孔径，同步获得了490 fs的近变换极限脉冲宽度和90 μm的近衍射极限焦斑，与等尺寸的非拼接光栅压缩器的结果非常接近。
The capability of chirped-pulse compression and beam focusing of an object-image-grating self-tiling grating compressor is demonstrated in an optical parametric chirped-pulse amplification laser for the first time. Probe lasers for tiling error adjustments, which are generally required by the traditional tiled-grating compressor, are not needed in our demonstration any more. With the aid of the double-sized effective optical aperture of the second grating in the compressor, a 490 fs near-transform-limit pulse duration and a 90 μm near-diffraction-limit focal spot are obtained, synchronously, which are very close to the ones achieved by a non-tiled grating compressor with equal-sized individual gratings.
