Why are pulsed lasers are the main tool used in nonlinear optics applications, instead of CW sources?

Why we often use pulsed lasers for nonlinear optics applications (such as SHG) instead of continuous wave lasers?

Self-phase modulation induced spectral broadening

How does one explain the fact that a pulse that has its phase modulated through SPM, generates new frequencies? How does the phase modulation affect the electrons so they emit not only the frequencies ...

How to find Intensity from field of train of pulses?

Is the intensity given by $I = E_{tot}(\omega)E_{tot}(\omega)^\ast$? Or should the intensity $I$ be each $I = \sum(|E(\omega)|^2)$, squared separately? The detector will integrate over time, but the ...

Max temperature that can be obtained from radiation source when nonlinear interaction with matter is important?

Using a black body radiation as furnace it is usually said that the max achievable $T$ is limited to the T of the source. So a source of 3000K can not be used to heat a body above 3000K. A long ...
