Abstract

We study a model of a far-infrared laser that was recently shown to explain a number of experimental results adequately. In a systematic way we perform linear stability analyses analytically. This determines up to four bifurcation diagrams in steady state, two of which are rather exceptional: In one case the whole branch of finite intensity is unstable, in the second case the low-intensity domain of the finite steady state is unstable. In both these cases the laser displays periodic or chaotic output without ever reaching a stable steady output.
