Uphando olutsha malungai-laser enobubanzi obumxinwa
I-laser enobubanzi obumxinwa ibalulekile kwiintlobo ngeentlobo zezicelo ezifana nokubona ngokuchanekileyo, i-spectroscopy, kunye nesayensi ye-quantum. Ukongeza kububanzi be-spectral, imo ye-spectral nayo yinto ebalulekileyo, exhomekeke kwimeko yesicelo. Umzekelo, amandla kumacala omabini omgca we-laser anokubangela iimpazamo ekulawuleni kwe-qubits kwaye achaphazele ukuchaneka kweewotshi zeathomu. Ngokuphathelele ingxolo ye-frequency ye-laser, izinto ze-Fourier eziveliswa yimitha ezenzekelayo engena kwi-ilezaImowudi idla ngokuba ngaphezulu kwe-105 Hz, kwaye ezi zinto zimisela i-amplitudes kumacala omabini omgca. Ukudibanisa i-Henry enhancement factor kunye nezinye izinto, umda we-quantum, oko kukuthi umda we-Schawlow-Townes (ST), uyachazwa. Emva kokususa iingxolo zobugcisa ezifana nokungcangcazela kwe-cavity kunye nokushukuma kobude, lo mda umisela umda ophantsi wobubanzi bomgca obusebenzayo obunokufezekiswa. Ke ngoko, ukunciphisa ingxolo ye-quantum linyathelo elibalulekileyo kuyilo lweiileyiza ezinobubanzi obumxinwa.
Kutshanje, abaphandi baphuhlise iteknoloji entsha enokunciphisa ububanzi bomgca we-laser ngaphezulu kwamawaka alishumi. Olu phando lunokutshintsha ngokupheleleyo amasimi e-quantum computing, iiwotshi ze-athomu kunye nokufunyanwa kwamaza anomtsalane. Iqela lophando lisebenzise umgaqo wokusasaza kweRaman okhuthazwayo ukuze ii-laser zivuse ukungcangcazela okuphezulu ngaphakathi kwezinto. Isiphumo sokunciphisa ububanzi bomgca siphezulu kangangamawaka kuneendlela zemveli. Ngokwenyani, kufana nokucebisa itekhnoloji entsha yokucoca i-laser spectral enokusetyenziswa kwiindidi ezahlukeneyo zee-laser zokufaka. Oku kubonisa impumelelo ebalulekileyo kwicandelo leiteknoloji yelaser.
Le teknoloji intsha isombulule ingxaki yotshintsho lwexesha lokukhanya okungacwangciswanga oluncinci olubangela ukuba ubumsulwa kunye nokuchaneka kwemitha yelaser yehle. Kwilaser efanelekileyo, onke amaza okukhanya kufuneka ahambelane ngokugqibeleleyo - kodwa eneneni, amanye amaza okukhanya angaphambili okanye emva kwamanye, nto leyo ebangela ukuguquguquka kwisigaba sokukhanya. Oku kuguquguquka kwesigaba kuvelisa "ingxolo" kwi-spectrum yelaser - kuyawufiphaza umjikelo welaser kwaye kunciphisa ubumsulwa bayo bombala. Umgaqo wetekhnoloji yeRaman kukuba ngokuguqula ezi meko zingahambelaniyo zibe ziintshukumo ngaphakathi kwikristale yedayimani, ezi ntshukumo zifunxwa ngokukhawuleza kwaye ziphele (ngaphakathi kwe-trillionths ezimbalwa zomzuzwana). Oku kwenza amaza okukhanya aseleyo abe ne-oscillations ethambileyo, ngaloo ndlela efikelela kubumsulwa obuphezulu be-spectral kwaye ivelise isiphumo esincinci kakhulu kwi-i-spectrum yelaser.
