Kupita patsogolo kwakukulu, asayansi apanga gwero latsopano lowala kwambiri!

Njira zowunikira ndi zofunika kwambiri kwa anthu amakono chifukwa zimalola kuzindikira mwachangu komanso motetezeka zinthu mu zolimba, zamadzimadzi kapena mpweya. Njirazi zimadalira kuwala kumagwirizana mosiyana ndi zinthu izi m'madera osiyanasiyana a sipekitiramu. Mwachitsanzo, kuwala kwa ultraviolet kumakhala ndi mwayi wopita ku kusintha kwamagetsi mkati mwa chinthu, pamene terahertz imakhudzidwa kwambiri ndi kugwedezeka kwa maselo.

Chithunzi chojambula chapakati pa infrared pulse spectrum kumbuyo kwa gawo lamagetsi lomwe limapanga pulse

Ukadaulo wambiri womwe wapangidwa m'zaka zapitazi wathandizira ma hyperspectroscopy ndi kujambula, kulola asayansi kuwona zochitika monga machitidwe a mamolekyu akamapinda, kuzungulira kapena kunjenjemera kuti amvetsetse zolembera za khansa, mpweya wowonjezera kutentha, zoipitsa, komanso zinthu zovulaza. Ukadaulo wowoneka bwino kwambiriwu watsimikizira kuti ndi wothandiza m'malo monga kuzindikira chakudya, kuzindikira kwachilengedwe, komanso chikhalidwe chachikhalidwe, ndipo atha kugwiritsidwa ntchito pophunzira kapangidwe ka zinthu zakale, zojambula, kapena zosema.

Vuto lomwe lakhalapo kwa nthawi yayitali lakhala kusowa kwa magwero a kuwala kophatikizika komwe kumatha kuphimba mawonekedwe owoneka bwino komanso kuwala kokwanira. Ma Synchrotrons atha kupereka mawonekedwe owoneka bwino, koma alibe kulumikizana kwakanthawi kwa ma laser, ndipo kuwala kotereku kungagwiritsidwe ntchito m'malo ogwiritsira ntchito ambiri.

Mu kafukufuku waposachedwapa wofalitsidwa mu Nature Photonics, gulu lapadziko lonse la ofufuza ochokera ku Spanish Institute of Photonic Sciences, Max Planck Institute for Optical Sciences, Kuban State University, ndi Max Born Institute for Nonlinear Optics ndi Ultrafast Spectroscopy, pakati pa ena, lipoti. chophatikizika, chowala kwambiri chapakati pa infrared driver gwero. Imaphatikiza mphete yotsutsa-resonant photonic crystal fiber yokhala ndi kristalo wanovel nonlinear. Chipangizochi chimapereka mawonekedwe ogwirizana kuchokera ku 340 nm mpaka 40,000 nm ndi kuwala kowoneka bwino maulendo awiri kapena asanu apamwamba kuposa chipangizo chimodzi chowala kwambiri cha synchrotron.

Kafukufuku wamtsogolo adzagwiritsa ntchito nthawi yocheperako ya gwero lamphamvu kuti ayese kusanthula kwanthawi yayitali pazinthu ndi zida, ndikutsegulira njira zatsopano zoyezera njira zama multimodal m'malo monga mawonekedwe a mamolekyulu, chemistry kapena fizikiki yolimba, ofufuzawo adatero.
