Abstract :
A theoretical analysis of collinear acousto-optical diffraction of ultra-short laser pulses for strong interaction is presented. The model simultaneously considers Bragg diffraction and group delay of wave packets. The new theoretical approach reveals transformation of the pulse envelope and pulse spreading even in a medium without group delay dispersion. These results are crucial for precise characterisation of acousto-optical dispersive delay lines.
