By tuning the beam intensity, the effect of anomalous dispersion can be cancelled out.

By performing similar experiments at longer wavelengths, for which the crystal has anomalous dispersion, it should be possible to generate bright 3D solitons — one of the major goals in the field of nonlinear optics.

Here they will find the problem solved for any number of particles and intervening springs, and the solution applied to an extension of the massive molecule which von Helmholtz imbedded in the elastic ether, and used to explain anomalous dispersion.

This has been called anomalous dispersion, and similar effects have been observed in iodine and sodium vapours, and in solutions of colours derived from aniline which exhibit surface colour.

Sellmeier's equation may also be modified to apply to the case of anomalous dispersion.
