Resumen:
In this work, the first and second order effects for reflected and transmitted pulses with a Gaussian distribution of frequenciesare analytically developed and interpreted. They show some peculiar characteristics that bear certain parallelism with those ofmonochromatic beams with a Gaussian distribution of amplitudes. However, when the former are considered, the results of the firstand second order effects obtained analytically are more difficult to interpret and are clearly limited by the principle of causality. Weshow that pulses show some peculiar characteristics when they reflect and transmit through linear media: time delay, shifting of themean frequency and modification of the pulse width. In addition to these effects we show and analyze the unexpected presence ofchirping when a simple structure of non-dispersive materials is considered
