For RTP/KTP our coefficients of linear thermal expansion at 305 K are: $\\alpha_x=9.44/7.88\\times 10^{-6}$/K, $\\alpha_y=12.49/9.48\\times 10^{-6}$/K, $\\alpha_z=-4.16/0.02\\times 10^{-6}$/K. Our normalized thermo-optic coefficients $\\beta=(1/n)dn/dT$ at 632.8 nm and 305 K are: $\\beta_x=5.39/3.78\\times 10^{-6}$/K, $\\beta_y=7.11/5.24\\times 10^{-6}$/K, $\\beta_z=12.35/9.34\\times 10^{-6}$/K."},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.03964","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
