-[SDC IN CONTEXT OF WHITE LIGHT]
+White light sources are also interesting to consider in the context of spectral delay
+correction.  %
+White light is typically quite chirped, with lower frequency (redder) colors traveling ahead of
+high frequency (bluer) colors.  %
+Typically, white light might serve as a ``probe'' that interacts last with the sample.  %
+If a scanning monochromator is used, spectral delay correction could be employed such that each
+color within the white light pulse arrives at the same delay.  %
+If a fully coherent experiment is performed with chirped white light as one of the excitation
+pulses, the other pulses will provide a gating effect in time that isolates interaction from one
+frequency in the white pulse.  %
+This is similar to the gating that is accomplished using ``delay 1'' in the TOPAS-C OPAs (see
+section  ...).  %
+By gating in this way, a \emph{frequency} axis along the white light dimension could be scanned
+using a delay stage.  %
+COLORS' has taken this idea to it's logical conclusion, with support for ``OPAs'' that are actually
+controlled by delay stages, although the idea has not yet been realized in practice.  %
