中文摘要	we examine the absorption of a weak probe beam in a laser-driven tripod-type atom with three closely lying ground levels, where both the driving and probe lasers interact simultaneously with the three transitions. the effects of spontaneously generated coherence (sgc) are taken into account. we introduce dipole moments in the dressed-state picture and the hamiltonian in terms of the dressed states describing the interaction between the probe and the atom. gain spectrum under various conditions are presented and analyzed. we show that the spectral structure and the gain amplitude of the probe are strongly influenced by the effect of sgc and the frequency separation of the three closely lying ground levels. the tripod-type atomic system with quantum interference in spontaneous emission can be simulated in the dressed-state picture of a coherently driven four-level n-type system where no sgc effect exists.
