Spatio-temporal shape and spectral distribution of pulse

Click For Summary
SUMMARY

The discussion centers on the concepts of spatio-temporal shape and spectral distribution of pulses, specifically addressing the relationship between temporal shape and spectral mode distribution. Participants clarify that the temporal shape refers to the intensity distribution of the pulse, and the Fourier transform is the mathematical tool that connects these two aspects. A well-defined temporal shape indeed leads to a fixed mode distribution, establishing a direct correlation between the two concepts.

PREREQUISITES
  • Understanding of Fourier Transform principles

Hi, everyone.

Can someone help me to understand pulse?

What is the meaning of temporal shape? is it means the intensity distribution of the pulse is following the shape?

What is the relationship between temporal shape and spectral mode distribution?

Is that the Fourier transform makes them together? If this is true, then if the temporal shape of the pulse is well defined, then the mode distribution is also fixed?

Thanks for helping
