ResumoWe report the theoretical interpretation of Lorenz-like behavior recently observed for the first time in a laser by Weiss and Brock [Phys. Rev. Lett. 57 (1986) 2804]. By means of a three-level laser model it is shown that in an optically-pumped far-infrared laser, coherent pumping effects are partially smeared out by Doppler broadening and as a result Lorenz-like dynamics may show up in some physical observables such as laser intensity.
