摘要: The nonlinear response to applied fields of a four-level Y-type atomic system is investigated. effect laser intensity and quantum interference induced by spontaneous emission on optical bistability, multi-stability Kerr nonlinearity then discussed. It found that the threshold bistability can substantially be reduced interference. So, an enhanced with absorption achieved.
