论文摘要
我们研究了带有三光子激发方案的原子蒸气中rydberg状态的电信波长光谱。两个激光器为780 nm和776 nm用于将蒸气单元中的rubidium-85原子泵送到$ 5D _ {\ Mathrm {5/2}} $状态，从中，O-Band Telecommunication Wavellength在O-Band tecommunication wavelength中的探头梁1292 nm驱动到$ 21F} $ 21F _ {瑞德伯格州。我们研究了泵激光器功率的探针光谱。基于4级理论模型的仿真捕获了实验结果的主要特征。这项光谱研究为将来的实验铺平了道路，即通过Rydberg原子在光纤和无线电传输之间建立直接联系。
We study telecom-wavelength spectra of a Rydberg state in an atomic vapor with a three-photon excitation scheme. Two lasers of 780 nm and 776 nm are used to pump Rubidium-85 atoms in a vapor cell to the $5D_{\mathrm{5/2}}$ state, from which a probe beam of 1292 nm in the O-band telecommunication wavelength drives a transition to the $21F_{\mathrm{7/2}}$ Rydberg state. We investigate the probe spectra over the power of pump lasers. The simulation based on a 4-level theoretical model captures the main features of the experimental results. This spectroscopic study paves the way for future experiments of making a direct link between fiber optics and radio transmission via Rydberg atoms.
