%X A system consisted of a three-level quantum dot coupled to a single mode of an optical microcavity is investigated.Using the numerical calculation method,the net stimulated emission dynamical evolution with the variation of the coupling strength between the quantum dot and the single mode of the optical microcavity is studied,which is based on quantum-optical master equations. The effect of the decay rate between the laser levels on the net stimulated emission is also studied. When the coupling strength between the quantum dot and the single mode of the optical cavity is larger, the net stimulated emission is prone to a saturation curve sooner. These saturation curves get to a limit value with the increasing value of the coupling strength sooner. The net stimulated emission curves show the opposite law with the increasing value of the decay rate between the laser levels.
