So many concepts are made understandable
when pictures are available to help explain them.
Collected
below are links to a handful of animations that are useful for the
demonstration of subtle ideas. Streaming video is not yet
available, so they will need to be downloaded. Files may be
in
.wmv or .avi format.
The first animation shows the interactions between
an
electron cloud and a sequence of short light pulses. Shown in
this animation is a progression of coherences formed by three pulses
that are resonant with different transitions. Download it here.
A more detailed narration is forthcoming, but is available
for
now in the associated Journal of Physical Chemistry Letters Perspectives
video. Also
available is the extended, dramatic, director's cut--no narration, but full
musical score.
The second animation shows the path of our three
picosecond pulses as they enter the sample. Notice that they
create a non-linear polarization that emits light (shown as a white
pulse) in the phase-matched output direction of interest.
