“…As is well known that the transient response of atomic system plays a potential role in the optical switch, dynamical properties of the optical spectra, and so on. There are some theoretical and experimental works on the transient properties of the three-level systems, [34][35][36][37][38][39][40] but all these works did not include the effects of SV. To our knowledge, the transient response in a _-type three-level atomic medium with the SV has not yet to be addressed.…”

In this paper, the effects of the squeezed vacuum (SV) on the transient response in a _-type three-level atomic medium are investigated. We find that the properties of transient process can be greatly affected by the SV whether the vacuuminduced coherence (VIC) exists or not. The combined influence of the SV and the VIC can dramatically modify the transient absorption and gain. Especially, the transient gain can be almost eliminated in the absence of VIC. And the response time from the transient to the steady situation is dependent on the SV. When including the VIC, the transient and steady optical properties display a reverse variation with the SV. Besides, it is shown that the considerable steady state population without inversion can be always induced by the SV. #
