The Laser — Trailblazer of Synergetics

  • Conference paper
Book cover Coherence and Quantum Optics IV

Abstract

In my paper I want to discuss how a thorough theoretical study of the laser process has led us to understand basic mechanisms of self-organization in physics, chemistry, biology and other sciences. A typical laser [1] consists of a rod of active material (compare fig. 1) with two mirrors at its endfaces. The laser-active atoms of the material are pumped energetically from the outside and emit laser light through one of the mirrors. The two mirrors form a Perot-Fabry-interferometer which allows only for those modes, whose wavelengths obey the relation (fig. 2)

While stability (or instability) criteria (see in particular [8]) are important to find “instabilities,” synergetics goes far beyond that, for instance, treating the question of what happens at the instability point (where also fluctuations are to be considered) and which new structures evolve.
