摘　　要：应用最近发展的量子耗散理论 ,研究了耗散对简单三能级体系的受激拉曼绝热转移过程的影响 ,并与pump dump过程比较 .计算结果表明 ,受激拉曼绝热转移的机制能很好地抑制中间态的弛豫与涨落的影响 .Using our recently developed quantum dissipation theory, we study the influence of dissipation on the population transfer efficiency between the stimulated Raman adiabatic passage ( STIRAP) and the pump-dump passage in a simple three-level Lambda system. By comparison, STIRAP is found to be relatively insensitive to the relaxation and fluctuation of the intermediate state. Numerical results also demonstrate the applicability of the new quantum dissipation theory for studying the correlated driving-dissipation dynamics problems.
