摘要
主要研究了单缀饰四波混频Autler-Townes分裂的相干控制。首先通过扫描探测场失谐的方式获得单缀饰四波混频信号的一阶Autler-Townes分裂;紧接着研究了一阶Autler-Townes分裂位置和宽度与缀饰场功率和失谐的定量关系。研究发现在缀饰场大失谐处,一阶Autler-Townes分裂的宽度随缀饰场功率呈现非线性变化过程,而当缀饰场位于共振频率附近则表现为线性过程。研究表明,通过选择缀饰场功率和失谐可实现对一阶Autler-Townes分裂位置和宽度的灵活控制。
In this paper,it is presented in details that the coherent control of single-dressed four-wave Mixing(FWM)Autler-Townes(AT)splitting.Firstly,The first-order AT splitting of FWM signal is observed.Also,the distance and position of AT splitting are calculated.Moreover,it shows the nonlinear or linear evolution by controlling the power and frequency of the dressing field.At large detuning,the distance increases nonlinearly with the power and frequency of the dressing field,while linearly with the power around resonant frequency.
