Only the sum of the two wave vectors must be normal to the cell, making the two-photon scheme highly versatile. A comparison is provided between the Dicke narrowing with copropagating fields, and the residual Doppler-broadening occurring with counterpropagating geometries. The experimental feasibility is discussed on the basis of a first observation of a two-photon resonance in a 300 nm-","authors_text":"Daniel Bloch (LPL), Gabriel Dutier (LPL), Isabelle Maurin (LPL), Ismah\\`ene Hamdi (LPL), Martial Ducloy (LPL), Petko Todorov (LPL), Solomon Saltiel (LPL)","cross_cats":[],"headline":"","license":"","primary_cat":"physics.atom-ph","submitted_at":"2005-06-03T12:10:05Z","title":"Dicke Coherent Narrowing in Two-Photon and Raman Spectroscopy of Thin Vapour Cells"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"physics/0506025","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:60869544159fa1b057501c8fce99b1ea7eb1dc72fc3b50757974e572c40ca709","target":"record","created_at":"2026-05-18T01:08:47Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"4076ad39a6b7ba3f7bebe3335b608ad87e9b837a772336fca966b15a04d318f6","cross_cats_sorted":[],"license":"","primary_cat":"physics.atom-ph","submitted_at":"2005-06-03T12:10:05Z","title_canon_sha256":"dff49034c29115b86fdff7ce745a5778018650cf1c883f4e3d1fc50e6cce6f6d"},"schema_version":"1.0","source":{"id":"physics/0506025","kind":"arxiv","version":1}},"canonical_sha256":"14573c4ddbf16a90e775bb558855571a15c9c3905ca7a86735665585ba9eb955","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"14573c4ddbf16a90e775bb558855571a15c9c3905ca7a86735665585ba9eb955","first_computed_at":"2026-05-18T01:08:47.018312Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:08:47.018312Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m3gYvzNWEYi3bGcanvJit9yLyzbUqsd5ZvxpmOBeSdh9B/7WqcrxXvbWAa84fGxwTQ5tT4je9jraYLfjd6a0CQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:08:47.019047Z","signed_message":"canonical_sha256_bytes"},"source_id":"physics/0506025","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:60869544159fa1b057501c8fce99b1ea7eb1dc72fc3b50757974e572c40ca709","sha256:84b9af08e0f517f0e7616ed5392b20572b34ab45888e5845e0453893bc4abded"],"state_sha256":"bbcce3b04e94b0934331e4d749ce03f16273996791c29ffe9f61ffc77e00115e"}
