The theoretical description has three main parts.

Although the concept of laser linewidth can have varied theoretical descriptions here this article provides a simple experimental description.

The variation in the five following parameters should be included in this theoretical description.

A more theoretical description involves a quantity known as radiation stress.

In fact, there are still some types of sub-Doppler signals for which there so far are no adequate theoretical description.

This article is intended for those who are interested in the theoretical description of quantum process of photodetection.

Helicity is a useful concept in theoretical descriptions of turbulence.

Therefore, it is open for many phenomena of media related communication, their theoretical description and empirical substantiation.

The theoretical description of the physical phenomena required the integration of concepts from relativity and quantum theory.

Their theoretical description is important not only from a fundamental point of view, but also in order to generate new and improved designs.
