Van Hove singularities play a significant role in understanding optical intensities in single-walled nanotubes (SWNTs) which are also quasi-1D systems.

(This condition assumes a focussing Kerr nonlinearity, whereby refractive index increases with optical intensity.)

As a consequence of optical intensity, chromatic vibration, and rhythmic movement, the picture plane seems to expand dynamically outwards.

His feeling for nature is realized as a vivid optical intensity and his tactile responsiveness produced a generous painterly physicality.

The gain G of the amplifier is defined as the optical intensity I at position z divided by the input intensity:

At best, optical intensity goes hand in hand with divine immanence, as in "Mirror Forest," in which greenish sunlight pours meltingly through a grove of young trees (Johnson).

At high optical intensities, above 2 megawatts per square centimeter, when a fiber is subjected to a shock or is otherwise suddenly damaged, a fiber fuse can occur.

Silicon has a focusing Kerr nonlinearity, in that the refractive index increases with optical intensity.

It is a nonlinear-optical process, where an appropriate crystal material is quickly electrically polarized at high optical intensities.

Most materials show some saturable absorption, but often only at very high optical intensities (close to the optical damage).
