Considering the atomic coherences and injected classical field, we derived
the generalized Lorenz-Haken equation (GLHE) by using the technique of quan
tum Langevin operator. The dynamics of this equation is then studied numeri
cally, and the results show that the atomic coherences and injected field c
an inhibit the chaos of the field in the cavity. (C) 2001 Elsevier Science
