Miniaturization of these sensors is primarily limited by requirements of the lasers used. Here\nwe demonstrate a three-photon sensing scheme using a J-shaped energy level coupling that can be achieved\nusing external cavity diode lasers, without the need for a doubling crystal or tapered amplifier. In the low\nlaser power regime, we demonstrate a full-width at half-maximum linewidth of 1.3 MHz. We demonstrate that\nfor RF field electrometry using conventional heterodyne techniques, we can detect 4.7 GHz at a sensitivity of\n27 \u03bcV m\u22121 Hz\u22121/2, comparable to that of two-photon detection schemes which require the use of a tapered\namplifier. We also investigate a modified scheme where the probe laser is locked to a different hyperfine state,\nthus measuring the two-photon EIT in the other two lasers via the change in population of this separate state\ndue to repumping. In this scheme we find the sensitivity for a 4.7 GHz field to be 39 \u03bcV m\u22121 Hz\u22121/2, and\ndemonstrate that the amplitude scaling with probe power offers a different saturation profile than the linked\nJ-scheme counterpart.", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/4116_README.txt", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig2.csv", "mediaType": "text/csv"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig2.csv.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig3a.csv", "mediaType": "text/csv"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig3a.csv.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig3b.csv", "mediaType": "text/csv"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig3b.csv.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig5.csv", "mediaType": "text/csv"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig5.csv.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig6.csv", "mediaType": "text/csv"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig6.csv.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig7.csv", "mediaType": "text/csv"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-4116/Fig7.csv.sha256", "mediaType": "text/plain"}], "identifier": "ark:/88434/mds2-4116", "issued": "2026-08-24", "keyword": ["Rydberg atoms", "atomic physics", "electric field", "fields strength", "receivers", "volts/meter"], "landingPage": "https://data.nist.gov/od/id/mds2-4116", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2026-08-13 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "theme": ["Physics:Atomic, molecular, and quantum", "Physics:Spectroscopy"], "title": "Data associated with \"Electromagnetically induced transparency and population repump readout of Rydberg states of Cs atoms in a J-scheme\""}
