ABSTRACT:
A system and/or method for temporal profiling of an incident laser pulse. The system and/or method includes a laser beam source for providing the incident laser pulse and a Bragg grating (BG) coupled to receive the incident laser pulse. The BG includes a distribution of diffraction efficiency density at various depths within the BG and provides a plurality of diffracted beamlets from the incident laser pulse. The system and/or method combines the diffracted beamlets into a single temporally shaped laser beam.
