Kupita patsogolo kwakukulu, asayansi apanga gwero latsopano la kuwala kogwirizana ndi kuwala kwakukulu!

Njira zowunikira kuwala ndizofunikira kwambiri pa chikhalidwe cha masiku ano chifukwa zimathandiza kuzindikira mwachangu komanso motetezeka zinthu zomwe zili mu zinthu zolimba, zamadzimadzi kapena mpweya. Njirazi zimadalira kuwala komwe kumagwirizana mosiyana ndi zinthuzi m'magawo osiyanasiyana a sipekitiramu. Mwachitsanzo, sipekitiramu ya ultraviolet imatha kulowa mwachindunji ku kusintha kwamagetsi mkati mwa chinthu, pomwe terahertz imakhudzidwa kwambiri ndi kugwedezeka kwa mamolekyulu.

Chithunzi chaluso cha mid-infrared pulse spectrum kumbuyo kwa mphamvu yamagetsi chomwe chimapanga pulse

Maukadaulo ambiri omwe apangidwa kwa zaka zambiri athandiza hyperspectroscopy ndi kujambula zithunzi, zomwe zathandiza asayansi kuwona zinthu monga momwe mamolekyu amachitira akamapindika, kuzungulira kapena kugwedezeka kuti amvetsetse zizindikiro za khansa, mpweya woipa, zoipitsa, komanso zinthu zovulaza. Maukadaulo oterewa akhala othandiza kwambiri m'magawo monga kuzindikira chakudya, kuzindikira za biochemical, komanso cholowa cha chikhalidwe, ndipo angagwiritsidwe ntchito kuphunzira kapangidwe ka zinthu zakale, zojambula, kapena ziboliboli.

Vuto lomwe lakhalapo kwa nthawi yayitali ndi kusowa kwa magwero ang'onoang'ono a kuwala omwe amatha kuphimba ma spectral range ambiri komanso kuwala kokwanira. Ma synchrotron amatha kupereka spectral coverage, koma alibe mgwirizano wa nthawi wa ma laser, ndipo magwero otere a kuwala angagwiritsidwe ntchito m'malo akuluakulu ogwiritsa ntchito.

Mu kafukufuku waposachedwa wofalitsidwa mu Nature Photonics, gulu 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, akunena za gwero laling'ono komanso lowala kwambiri la mid-infrared driver. Limaphatikiza ulusi wa kristalo wa ring anti-resonant photonic womwe umalowa mpweya ndi kristalo watsopano wosalowa mzere. Chipangizochi chimapereka mawonekedwe ogwirizana kuyambira 340 nm mpaka 40,000 nm ndi kuwala kwa spectral kwa magulu awiri kapena asanu kuposa chimodzi mwa zida zowala kwambiri za synchrotron.

Kafukufuku wamtsogolo adzagwiritsa ntchito nthawi yochepa ya kuwala kwa gwero la kuwala kuti achite kusanthula kwa zinthu ndi zinthu zomwe zili munthawi yeniyeni, ndikutsegula njira zatsopano zoyezera zinthu zambiri m'malo monga ma molecular spectroscopy, physical chemistry kapena solid state physics, ofufuzawo adatero.
