我们介绍并演示了一种简单、紧凑、自动对准的超短脉冲压缩器，它仅使用单个衍射元件——光栅或棱镜（棱镜上的光栅）。该设计自动具有单位光束放大率，并自动为脉冲提供零时空畸变，从而避免空间线性调频、角色散、脉冲前倾斜和所有其他一阶时空畸变。它仅由三个元件组成：衍射元件、角锥棱镜和车顶镜。它的尺寸只有同类双光栅压缩器的一半，可以通过角锥的小平移提供大量的负群延迟色散。通过改变角立方体位置，该器件可以对大带宽和小带宽的脉冲进行操作。使用棱镜作为衍射元件，可以补偿高达三阶的材料色散，并且我们演示了对 800 nm 脉冲的 10 m 光纤的补偿。 (C) 2010 美国光学学会
We introduce and demonstrate a simple, compact, and automatically aligned ultrashort-pulse compressor that uses only a single diffraction element-a grating or a grism (a grating on a prism). This design automatically has unity beam magnification and automatically contributes zero spatiotemporal distortions to the pulse, thus avoiding spatial chirp, angular dispersion, pulse-front tilt, and all other first-order spatiotemporal distortions. It is comprised of only three elements: a diffraction element, a corner cube, and a roof mirror. Half the size of comparable two-grating compressors, it can provide large amounts of negative group-delay dispersion with small translations of the corner cube. The device can operate on pulses with both large and small bandwidths by varying the corner-cube position. Using a grism as the diffraction element, material dispersion up to the third order can be compensated, and we demonstrated compensation for 10 m of optical fiber for 800 nm pulses.
