Babban aikilaser mai sauri sosaigirman yatsa

A cewar wani sabon labarin da aka buga a mujallar Science, masu bincike a Jami'ar City ta New York sun nuna wata sabuwar hanya ta ƙirƙirar ayyuka masu inganci.lasers masu sauriakan nanophotonics. Wannan ƙaramin yanayin da aka kullelaseryana fitar da jerin bugun haske mai gajarta sosai a tazara tsakanin daƙiƙa biyu (trillionths of a seconds).

Yanayin kullewa mai sauri sosaina'urorin laserzai iya taimakawa wajen buɗe sirrin lokutan yanayi mafi sauri, kamar samuwar ko karya haɗin kwayoyin halitta yayin halayen sinadarai, ko yaɗuwar haske a cikin kafofin watsa labarai masu rikitarwa. Babban saurin gudu, ƙarfin bugun jini mafi girma, da kuma faɗin bakan lasers masu kulle yanayin suma suna ba da damar fasahar photon da yawa, gami da agogon atomic na gani, hoton halittu, da kwamfutoci waɗanda ke amfani da haske don ƙididdigewa da sarrafa bayanai.

Amma na'urorin laser masu ci gaba har yanzu suna da tsada sosai, kuma suna buƙatar wutar lantarki, waɗanda aka iyakance ga amfani da dakin gwaje-gwaje. Manufar sabon binciken ita ce mayar da wannan zuwa tsarin girma-girma wanda za a iya samar da shi da yawa kuma a tura shi a fagen. Masu binciken sun yi amfani da wani dandamali mai tasowa na kayan lithium niobate (TFLN) don tsara yadda ya kamata da kuma sarrafa bugun laser ta hanyar amfani da siginar lantarki ta rediyo ta waje a kai. Ƙungiyar ta haɗa babban ƙarfin laser na semiconductors na aji III-V tare da ingantaccen ƙarfin siffanta bugun jini na TFLN nanoscale photonic waveguides don haɓaka laser wanda ke fitar da babban ƙarfin fitarwa na watts 0.5.

Baya ga ƙaramin girmansa, wanda shine girman yatsa, sabon laser ɗin da aka nuna yana kuma nuna wasu halaye da laser na gargajiya ba za su iya cimmawa ba, kamar ikon daidaita daidai yawan maimaita bugun fitarwa akan kewayon megahertz 200 kawai ta hanyar daidaita wutar famfo. Ƙungiyar tana fatan cimma tushen tsefe mai daidaito ta hanyar sake fasalin laser mai ƙarfi, wanda yake da mahimmanci don fahimtar daidaito. Aikace-aikacen da ake amfani da su sun haɗa da amfani da wayoyin hannu don gano cututtukan ido, ko don bincika ƙwayoyin cuta masu haɗari a cikin abinci da muhalli, da kuma ba da damar kewayawa lokacin da GPS ta lalace ko babu.
