Figure A-6: The four prism sequence used for dispersion compensation in the Tsunami laser.
An input pulse with a positive chirp (red frequencies at the leading edge of the pulse)
experiences negative GVD (red frequencies have longer group delay time) in the prism
sequence. The net effect is that the prism sequence compensates for the positive GVD
and produces a pulse which has no chirp. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . A-8
