We experimentally demonstrate that high energy ultrashort pulses can be compressed through self-phase-modulation in hollow planar waveguides. The beam is guided in one transverse dimension and propagates free in other, allowing scalability to higher energies.
A single-prism/corner-cube pulse compressor significantly simplifies alignment and tuning. Angle-tuning the prism wavelength-tunes and translating a corner cube varies group-delay dispersion, maintaining zero angular dispersion, zero pulse-front tilt, zero spatial chirp, and unity magnification.
