Abstract
The light-induced drift velocity of optically active atoms immersed in a buffer gas sometimes changes sign at some temperature. It is pointed out that the density of the active atoms and the temperature of the system form a nonlinear dynamical system that may exhibit instabilities. These may show up as an oscillatory behavior of these quantities as a function of time. A possible realization in the case of alkali-metal atoms is discussed.
