The angle-resolved capability is utilized to control pump and probe wavevectors, while real space imaging enables co-localization of the collection spots for linear and ultrafast experiments. Compression of pulses down to 20 fs is achieved. We demonstrate the capabilities of this approach on an exfoliated WSe$_2$ monolayer on Si/SiO$_2$. The setup is suited to investigate excitons and exciton-polaritons in 2D Mat","authors_text":"Anton Trenczek, H\\'el\\`ene Seiler, Jasper Wilhelm Schwering, Matteo Russo, Pavel Trofimov, Trideep Kawde","cross_cats":["physics.ins-det"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-07-02T13:49:53Z","title":"Coherent two-dimensional electronic spectroscopy integrated with confocal back focal plane microscopy"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.02178","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":"sha256:752d34a59cc917847298e8769ba2754dfe88c32e3bf77ba74d633d955fb9f02e","target":"record","created_at":"2026-07-03T01:17:44Z","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":"a25b3ff89935c3c6d7dfcf886eebec1b1012a610f0948c6f0fce3fc0d0e3f856","cross_cats_sorted":["physics.ins-det"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-07-02T13:49:53Z","title_canon_sha256":"21671d8c75b52ef2a51cb94be11c0ab8162c86ff28d8c1ae026e2458a3cd770a"},"schema_version":"1.0","source":{"id":"2607.02178","kind":"arxiv","version":1}},"canonical_sha256":"e9745ec8262259ebf04260a3192712819f212d0c9d7f25fb2680e52296534532","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e9745ec8262259ebf04260a3192712819f212d0c9d7f25fb2680e52296534532","first_computed_at":"2026-07-03T01:17:44.131466Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-03T01:17:44.131466Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9b2OCQr4Jzdp5/zY47B4NgOCtf1L1gqB29LsJjCt13ZwVCmQZWWqroYktB+9o5fudNk3H2dThQT6qE/w7HHJBw==","signature_status":"signed_v1","signed_at":"2026-07-03T01:17:44.131901Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.02178","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:752d34a59cc917847298e8769ba2754dfe88c32e3bf77ba74d633d955fb9f02e","sha256:cc54a9685d2cebeb82d820770e4932a1808b4a71bdc9884dd7904352c1534070"],"state_sha256":"84c47e21af14d964c30dd12bec2ed5d795aee7987b10136f3c40bfbf9e24b90a"}
