Large-aperture compression of picosecond laser pulses and bandwidth-limited radiation arising in a spatially periodic medium: theory and experiment

<title>3D structures and laser-induced dynamic self-organization processes in an organic medium with a long-range interaction</title>

“…Besides this instability effects, the effect of compression of laser pulses occurs as well when the radiation passes through the DFB-system 26,27 The phenomenon is determined by the dependence on the frequency of the propagation directions of diffracted (because of the grating) beams arid thus the DFB plays the role of dispersive delay line due to spatial periodicity of the medium.…”
