Fig. 1. Schematic of a plasma prism based on ionization of hydrogen gas in an additively manufactured gas cell^[25].

Fig. 2. Path of lower frequency (red) and higher frequency (blue) rays through the plasma-prism compressor.

Fig. 3. Allowed values of and such that for densities varying from 0.1 to 0.005 (colored lines, labeled).

Fig. 4. Third-order distortion for densities varying from 0.1 to 0.005 such that , showing that TOD needs to be compensated for.

Fig. 5. Effects of TOD on a bandwidth-limited pulse showing that corresponds to a severe TOD phase error.

Fig. 6. Full compression of a pulse with duration fs is simulated in OSIRIS using a plasma-prism system. The plasma density profile is plotted in yellow. Seven simulation outputs are plotted with timestamps. The dashed lines show the expected paths of frequency components.
