Query: Prospects of coherent control in turbid media: Bounds on focusing
  broadband laser pulses   We study the prospects of controlling transmission of broadband and
bi-chromatic laser pulses through turbid samples. The ability to focus
transmitted broadband light is limited via both the scattering properties of
the medium, and the technical characteristics of the experimental set-up. There
are two time scales, given by pulse stretching in the near- and far-field
regions, which define the maximum bandwidth of a pulse amenable to focusing. In
the geometric optics regime of wave propagation in the medium, a single set-up
can be optimal for focusing light at frequencies w and nw simultaneously,
providing the basis for the 1 + n coherent quantum control. Beyond the regime
of geometric optics, we discuss a simple solution for the shaping, which
provides the figure of merit for one's ability to focus simultaneously several
transmission modes.
