Lo que se logró es que la lectura de la señal sea total, con un contraste óptico del 100 por ciento. Para alguien de acá, esto puede traducirse en equipos médicos o de exploración más sensibles en unos años. Todavía está en etapa de laboratorio, y el paso a aparatos de uso real suele tardar bastante.","quienFirma":"Fraunhofer IAF (Alemania)","confianza":"revisado","consulta":{"pregunta":"¿Qué aplicación te interesa más?"}},"sello":{"hash":"c59610a1f6c896025453506dca6ddda2da12b84c63e3ecf3b296a6ce09ab166e","sello":"b7a494b9114ad7ec156f45abd020850c109405d3cd324456d282843b012dcf39","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6575411,"aleatorio":"a7742475a5c19e7b0de755e1e93ab199e8a74b0debccd309c012d09e043a62fb","tiempo":"2026-10-22T18:22:30.000Z"},"nist":{"cadena":2,"pulso":1994905,"salida":"46E0B61A11F04881E356799CC8735A5B23D4470AA70A59CED9B2387D7C329BF67511A2ECC2BAB7BA07D9FCEA497F2E576D575AE7C5A4665E7524A815E15BFE20","tiempo":"2026-10-22T18:22:00.000Z"},"noAntes":"2026-10-22T18:22:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 18:22:51 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Diamond laser system achieves 100% optical contrast in magnetic-field readout","descripcion":"Researchers at Fraunhofer IAF have developed a laser-enhanced quantum sensor that combines high magnetic-field sensitivity with a large dynamic range. Using laser threshold magnetometry, they improved the ratio of sensitivity and dynamic range by a factor of up to 590 compared with state-of-the-art approaches. The breakthrough is enabled by the first demonstration of 100% optical contrast, combined with strong laser readout signals. The results, published in Nature Communications, open up new prospects for medical diagnostics, navigation, and resource exploration.","pubDate":"Thu, 22 Oct 2026 14:20:08 EDT","url":"https://phys.org/news/2026-10-diamond-laser-optical-contrast-magnetic.html"},"indexado":"2026-10-22T18:22:13.551Z"}}
