Waxqabad sarelaser ultrafastxajmiga faraha faraha

Sida laga soo xigtay maqaal cusub oo dabool ah oo lagu daabacay joornaalka Sayniska, cilmi-baarayaasha Jaamacadda City ee New York waxay muujiyeen hab cusub oo lagu abuuro waxqabad sare.laser ultrafaston nanophotonics. Habkan la yareeyeyleysarkaWaxay soo saartaa taxane ah garaacyo ultra-gaaban oo isku xiran oo iftiin ah xilliyo udhaxeeya femtosecond (trillionths of the second).

Habka Ultrafast-ku xiranleysarkawaxay kaa caawin kartaa daah furka siraha waqtiyada ugu dhaqsaha badan dabeecadda, sida samaynta ama jebinta curaarta molecular inta lagu jiro falcelinta kiimikada, ama faafinta iftiinka warbaahinta qallafsan. Xawaaraha sare, xoojinta garaaca garaaca ugu sarreysa, iyo daboolida baaxadda ballaaran ee leysarka qaab-xiran ayaa sidoo kale awood u siinaya teknoolojiyad badan oo sawir-qaade ah, oo ay ku jiraan saacadaha atomiga, sawirka noolaha, iyo kombiyuutarada isticmaala iftiinka si ay u xisaabiyaan ugana baaraandegaan xogta.

Laakin kuwa ugu casrisan ee qaabka qufulan leysarka ayaa weli ah kuwo aad qaali u ah, nidaamyada desktop-ka awood u baahan oo ku kooban isticmaalka shaybaarka. Hadafka cilmi-baarista cusub ayaa ah in tan loo rogo nidaam cabbir-jibis ah oo la soo saari karo oo la geyn karo goobta. Cilmi-baadhayaashu waxay adeegsadeen madal maaddooyinka soo baxaya ee lithium-filim khafiif ah (TFLN) si ay si wax ku ool ah u qaabeeyaan oo ay si sax ah u xakameeyaan garaaca garaaca laysarka iyagoo isticmaalaya calaamadaha korantada ee soo noqnoqda raadiyaha dibadda. Kooxdu waxay isku dartay faa'iidada laysarka sare ee semiconductors fasalka III-V oo leh karti wax ku ool ah qaabeynta garaaca wadnaha ee TFLN nanoscale photonic waveguides si ay u horumariyaan leysarka soo saara awoodda ugu sarreysa ee 0.5 watts.

Marka lagu daro cabbirkeeda is haysta, oo ah cabbirka faraha caarada, laser-ka cusub ee la soo bandhigay ee hab-xidhan waxa kale oo uu soo bandhigayaa tiro hanti ah oo laysarka-dhaqameedku aanay gaadhi karin, sida awoodda si sax ah loogu habeeyo heerka soo noqnoqda ee garaaca garaaca wadnaha baaxad weyn oo ah 200 megahertz kaliya adoo hagaajinaya bamka hadda jira. Kooxdu waxa ay rajaynaysaa in ay gaadhaan il shanlo ah oo jajab ah, inta jeer ee xasiloon iyada oo loo marayo dib-u-habaynta awooda leysarka, taas oo muhiim u ah dareenka saxda ah. Codsiyada wax ku oolka ah waxaa ka mid ah isticmaalka taleefoonnada gacanta si loo ogaado cudurrada indhaha, ama lagu falanqeeyo E. coli iyo fayrasyada khatarta ah ee ku jira cuntada iyo deegaanka, iyo in la suurtageliyo navigation marka GPS uu dhaawacmo ama aan la heli karin.
