Phys. Rev. A 65, 023811 (2002) [6 pages]Optical bistability in lasers induced by active molecules with a large permanent dipole momentReceived 15 June 2001; published 15 January 2002 We study a single-mode laser system, whose active medium consists of molecules with a large difference between excited and ground electrical permanent-dipole moments. In this case, the Maxwell-Bloch equations are further coupled by nonlinear terms involving the ratio between this difference between the dipoles and the transition dipole moment. It is found that these new terms lead to multiple stationary solutions. From the linear stability analysis, we demonstrate the bistable (or multistable) character of the lasing solutions. © 2002 The American Physical Society URL:
