Abstract

We conduct the experimental investigation of arbitrarily shaped ultrashort pulse propagation through angularly dispersive systems, a pair of gratings, and a pair of prisms, in the linear regime. The propagation time has been explained by the net group delay in the context of centroid of energy arrival as the definition of the pulse propagation time. The temporal positions of the centroid of energy are apparently the same for both transform-limited coherent and arbitrary pulses, despite the fact that the pulses suffer severe distortion owing to strong group-velocity dispersion during propagation through the dispersive systems.
