... SPM leads to symmetric spectral broadening around ωo, whereas the self steepening term that leads to optical shock results in asymmetric spectral broadening of the pulse. Selfsteepening can be explained by the intensity-dependence of the group velocity [1]. As the intensity of a pulse increases from ...

... They are in an antibonding state. We could take silicon as an example. When two such free silicon atoms meet, they may bond together. They will do so because the bonding state is at a lower energy than what existed previously. The valence electrons have thus fallen into some kind of potential well, ...

... Most light waves vibrate in all planes that are perpendicular with respect to the direction of propagation. If the electric field vectors are restricted to a single plane by filtration of the beam with specialized materials, then the light is referred to as plane polarized with respect to the direct ...
