Extremely simple, compact, distortion-free, single-prism ultrashort-pulse compressor

Summary form only given. In this paper, we introduce an extremely simple, compact, and distortion-free single-prism pulse compressor using PBH71 and BK7 prisms. It simply involves a corner cube after the first (only) prism, yielding an inversion in the reflected beam and so effectively inverting the prism for the second pass. Then, using a periscope, it returns the beam through the prism and corner cube for four passes in all.
