对$5{S}_{1/2}\ensuremath{\rightarrow}5{P}_{3/2}$(激光波长780 nm)、$5{P}_{3/2}\ensuremath{\rightarrow}5{D}_{5/2}$(776 Nm)和$5{D}_{5/2}\ensuremath{\rightarrow}28{F}_{7/2}$(1260 Nm)三级联晶体的三光子电磁诱导透明和吸收特性进行了全面的研究。780 nm的探测光束和776 nm的修整光束通过RB室温蒸汽室进行对准，1260 nm的耦合光束与探测光束共对准或对准。研究了在776 nm光束的失谐范围内测量的几种情况下的EIT和EIA。通过数值求解Lindblad方程来模拟观察到的现象，并用与速度和失谐相关的修饰态的探测束吸收行为来解释结果。讨论了相互作用的时间效应。为了探索三光子里德堡电子内窥镜和电子内窥镜在微波电场诊断中的应用，将由信号源和频率倍增器产生的亚THz场应用于RB小室。100.633 GHz场强共振驱动$28{F}_{7/2}\ensuremath{\leftrightarrow}29{D}_{5/2}$跃迁，导致里德堡能谱和电子能谱产生奥特勒-汤斯分裂，并用来表征微波四倍频的性能。
A comprehensive study of three-photon electromagnetically induced transparency (EIT) and absorption (EIA) on the rubidium cascade $5{S}_{1/2}\ensuremath{\rightarrow}5{P}_{3/2}$ (laser wavelength 780 nm), $5{P}_{3/2}\ensuremath{\rightarrow}5{D}_{5/2}$ (776 nm), and $5{D}_{5/2}\ensuremath{\rightarrow}28{F}_{7/2}$ (1260 nm) is performed. The 780-nm probe and 776-nm dressing beams are counteraligned through a Rb room-temperature vapor cell, and the 1260-nm coupler beam is co- or counteraligned with the probe beam. Several cases of EIT and EIA, measured over a range of detunings of the 776-nm beam, are studied. The observed phenomena are modeled by numerically solving the Lindblad equation, and the results are interpreted in terms of the probe-beam absorption behavior of velocity- and detuning-dependent dressed states. Interaction-time effects are discussed. To explore the utility of three-photon Rydberg EIA and EIT for microwave electric-field diagnostics, a sub-THz field generated by a signal source and a frequency quadrupler is applied to the Rb cell. The 100.633-GHz field resonantly drives the $28{F}_{7/2}\ensuremath{\leftrightarrow}29{D}_{5/2}$ transition and causes Autler-Townes splittings in the Rydberg EIA and EIT spectra, which are measured and employed to characterize the performance of the microwave quadrupler.
