We report the experimental observation of energetically confined self-accelerating optical beams propagating along various convex trajectories. We show that, under an appropriate transverse compression of their spatial spectra, these self-accelerating beams can exhibit a dramatic enhancement of their peak intensity and a significant decrease of their… (More)
We analytically study the propagation dynamics of two-dimensional accelerating beams in a generalized way and propose an optimized method to enhance their peak intensities. Our theoretical analysis is confirmed by experimental results.
