Using Ytterbium highly-doped silica fiber with large mode area, more than 3 W of 997 nm signal was obtained with less than 2 % of ASE. These figures keep improving with operating wavelength, to reach more than 16 W and 0.03 % of ASE at 1017 nm. The optical signal to noise ratio exceeds 40dB for the worst case up to more than 60dB. In addition, relative intensity noise remains very low over the whole tu","authors_text":"Ad\\`ele Hilico (LP2N), Beno\\^it Gouhier (LP2N), Cl\\'ement Dixneuf (LP2N), Germain Guiraud, Giorgio Santarelli (LP2N), Nicholas Traynor","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2019-05-24T13:25:28Z","title":"Low intensity noise high-power tunable fiber-based laser around 1007 nm"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1905.10223","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":"sha256:85713b2f4bd12d0bbb94e318b87035256c5f69372bb76c08f9c59aac105f5504","target":"record","created_at":"2026-05-17T23:39:43Z","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":"6dcd35663b85bd3f69b858fb6c2bfa0ecd801d9da1ca1832a24cde2eb572b2ce","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.optics","submitted_at":"2019-05-24T13:25:28Z","title_canon_sha256":"c954843ad597a0c0a5c05fc641c6b05cb4cebf8ee5a87a03c9a092d817617316"},"schema_version":"1.0","source":{"id":"1905.10223","kind":"arxiv","version":1}},"canonical_sha256":"519be72d1afa271f1744e9099f0d3e50a98a6ddc178b8702edcbfd0f4bd036ae","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"519be72d1afa271f1744e9099f0d3e50a98a6ddc178b8702edcbfd0f4bd036ae","first_computed_at":"2026-05-17T23:39:43.453219Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:39:43.453219Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8OXwEYyYXpJLnPxMGM2afNGbf0mpVFD3/Y/s88fovASmOYo6hzsfMGpLJnHG6DELnGIXpIrp0Ro0kKVSl9hvBQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:39:43.453823Z","signed_message":"canonical_sha256_bytes"},"source_id":"1905.10223","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:85713b2f4bd12d0bbb94e318b87035256c5f69372bb76c08f9c59aac105f5504","sha256:5422c663601c2b9a80b5960d0d7d243a35895d08848c2cf69da6a929222f15f7"],"state_sha256":"d0823def1dad9da91dc776614f0213d1556b4b1e5ce06cbe08a36c4f75e43dfc"}
