Short Course in Laser – Lecture 2: Laser: A Fascinating Non-Linear System

Since its invention in 1960, the laser has revolutionized both the study of optics and our understanding of the nature of light, prompting the emergence of a new field, quantum optics. Surprisingly enough, such quantum optics phenomena hardly existed at the time that the laser was invented, and almost all optics effects could be fully understood by describing light as a classical electromagnetic field; the laser was no exception. This short course is devoted to presentation of the semi-classical approach where only the amplifying medium is described as a quantum system. It is not intended to be a specialized course, and will emphasize general physical phenomena of which the laser behaviour is a remarkable example.

This lecture on Laser: A Fascinating Non-Linear System describes how such a simple optical device can generate fascinating nonlinear phenomena at work in many different systems, not only in physics but in many other scientific fields and beyond.
