  We demonstrate a high throughput, large compensation range, single-prism
femtosecond pulse compressor, using a single prism and two roof mirrors. The
compressor has zero angular dispersion, zero spatial dispersion, zero
pulse-front tilt, and unity magnification. The high efficiency is achieved by
adopting two roof mirrors as the retroreflectors. We experimentally achieved ~
-14500 fs2 group delay dispersion (GDD) with 30 cm of prism tip-roof mirror
prism separation, and ~90.7% system throughput with the current implementation.
With better components, the throughput can be even higher.
