anomalous dispersion

noun

, Physics.

1. a sudden change in the refractive index of a material for wavelengths in the vicinity of absorption bands in the spectrum of the material.

Word History and Origins

Origin of anomalous dispersion¹

First recorded in 1880–85

Example Sentences

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

From Nature

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.

From Nature

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.

From Project Gutenberg

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.

From Project Gutenberg
