Laser Dynamics: Weak versus Strong Harmonic-Expansion Modelling

Abstract

Belkacem Meziane

This paper aims at to providing a self-consistent outline of new analytical prospects that deal with the laser dynamics issue, from which results that go beyond the well-known linear stability analysis are extracted. The method of investigation is rooted in weak and strong- harmonic Fourier-expansions applied to the laser equations when these operate under unstable conditions. Both routines are shown to apply equally well to the simple Lorenz-Haken model as well as to the much complex integro-differential Maxwell-Bloch equations
