The objective of my work was the realization of an experimental study bench on the quadratic propagations which can lead to a mutual trapping (spatial and temporal) of the beams at the fundamental and second harmonic frequencies. The originality of this research was to demonstrate, for the first time, the appearance and disappearance of one or more extreme events (2D quadratic spatial solitons) as a function of the monotonic increase of the initial power. These spatial nonlinear phenomena are accompanied by a spectral broadening as well as a temporal compression followed by a deterioration of the first pulse. Two applications have been realized, one on ultrafast temporal remodeling of short pulses, the other on the use of the broadband spec...
