Abstract:
Visualization of the energy density flux gives a unique insight
into the propagation properties of complex ultrashort pulses. This analysis,
formerly relegated to numerical investigations, is here shown to be an
invaluable experimental diagnostic tool. By retrieving the spatio-temporal
amplitude and phase we experimentally obtain the energy density flux
within complex ultrashort pulses generated by filamentation in a nonlinear
Kerr medium.
