Under strongest focusing conditions, microplasmas are shown to act as point-sources for broadband terahertz-to-far-infrared radiation, where the emission bandwidth is determined by the plasma density. Semi-analytical modeling allows us to identify scaling laws with respect to important laser parameters. In particular, we find that the optical-to-THz conversion efficiency crucially depends on the focusing conditions. We use this insight to demonstrate by means of Maxwell-consistent 3D simulations, that for only 10-$","authors_text":"Alisee Nguyen, Illia Thiele, Luc Berge, Pedro Gonzalez de Alaiza Martinez, Rachel Nuter, Stefan Skupin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2017-03-31T15:39:20Z","title":"Broadband terahertz emission from two-color fs-laser-induced microplasmas"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.10949","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:a9309aae68ae21c4d6d83c1ec6b7092d877ccb5cbdb28281adf10704a649baca","target":"record","created_at":"2026-05-18T00:30:45Z","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":"a2c76bf171f537298bb413468d05c281b98a3b85619485ef2dbe80054874962d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2017-03-31T15:39:20Z","title_canon_sha256":"f5b4415f57edcf02f9be85ee6b9dea8d35e8c8b9d125f1ff8508ea0af70faac4"},"schema_version":"1.0","source":{"id":"1703.10949","kind":"arxiv","version":1}},"canonical_sha256":"f0e2d2e033f9e11aecd47599cf73a2bf3f19e565121e1cb6c1376d7cf5626829","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f0e2d2e033f9e11aecd47599cf73a2bf3f19e565121e1cb6c1376d7cf5626829","first_computed_at":"2026-05-18T00:30:45.305834Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:30:45.305834Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hOQpGKsRVm4zkyLGLLO3vmvzazGCDBKhQwXawWQU1nKoan8MPQAMrdlptPdD+Zaq/f4JQ46D3XzjU+pph5n+DA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:30:45.306304Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.10949","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a9309aae68ae21c4d6d83c1ec6b7092d877ccb5cbdb28281adf10704a649baca","sha256:90c08148fc04c13e5c2579641f038bc233893e121d294ccb7428924a5d399071"],"state_sha256":"7ea9e8b3f378d23646ab1ec9f62425ba6ce962cbbe798cfc1b14b29a8209c5f7"}
