摘要:

本文基于一维的高斯单光子和双光子脉冲与单个二能级原子的相互作用模型,研究了单光子和双光子脉冲与原子的相互作用。原子响应的特征时间尺度是偶极弛豫时间1/伽马。因此,我们比较的非线性双光子相互作用的效果为10/伽马的长脉冲长度与短脉冲的$1/Γ$。我们的结果表明,非线性相互作用的影响是特别强的短脉冲长度的1/γ。

英文摘要:

We study the interaction of Gaussian one- and two-photon pulses with a single two-level atom based on a one-dimensional model of pulse propagation to and from the atom. The characteristic time scale of the atomic response is the dipole relaxation time 1/Gamma. We therefore compare the effect of the non-linear two-photon interaction for a long pulse length of 10/Gamma with a short pulse of $1/Γ$. Our results indicate that the effect of the non-linear interaction is particularly strong for the short pulse length of 1/Gamma.
