The control of pulse profiles with tunable temporal coherence

A new class of partially coherent pulse sources with Multi-Gaussian Schell-model (MGSM) correlations is proposed. The expression for the intensity distribution for the MGSM pulses generated by such sources on propagation through the dispersive media is derived. It is demonstrated that the pulse inte...

Description
Summary:A new class of partially coherent pulse sources with Multi-Gaussian Schell-model (MGSM) correlations is proposed. The expression for the intensity distribution for the MGSM pulses generated by such sources on propagation through the dispersive media is derived. It is demonstrated that the pulse intensity profile, in particular, the width of the flat center of pulse intensity profile and the peak intensity, can be controlled by adjusting the source temporal coherence. The obtained results have potential applications in pulse shaping for communication and media sensing or pulsed laser material processing. •The MGSM pulses with Multi-Gaussian Schell-model (MGSM) correlations are proposed.•The intensity distribution for the MGSM pulses is derived.•The pulse intensity profile can be controlled by adjusting the source temporal coherence.
