Ka'idar sanyaya laser da aikace-aikacensa ga ƙwayoyin sanyi
A fannin kimiyyar atom mai sanyi, aikin gwaji da yawa yana buƙatar sarrafa barbashi (daure atom na ionic, kamar agogon atom), rage su, da kuma inganta daidaiton ma'auni. Tare da haɓaka fasahar laser, sanyaya laser ya fara amfani da shi sosai a cikin atom mai sanyi.
A ma'aunin atomic, ainihin zafin jiki shine saurin da ƙwayoyin cuta ke motsawa. Sanyayawar laser shine amfani da photons da atoms don musayar motsi, ta haka ne sanyaya atoms. Misali, idan atom yana da saurin gaba, sannan ya sha photon mai tashi yana tafiya a akasin haka, to saurinsa zai ragu. Wannan kamar ƙwallon da ke birgima gaba a kan ciyawa ne, idan wasu ƙarfi ba su tura shi ba, zai tsaya saboda "juriya" da taɓa ciyawar ke haifarwa.
Wannan shine sanyayawar atoms ta hanyar laser, kuma tsarin yana da zagaye. Kuma saboda wannan zagayen ne atoms ke ci gaba da sanyaya.
A cikin wannan, mafi sauƙin sanyaya shine amfani da tasirin Doppler.
Duk da haka, ba dukkan kwayoyin halitta za a iya sanyaya su ta hanyar amfani da na'urar laser ba, kuma dole ne a sami "canjin yanayi" tsakanin matakan kwayoyin halitta don cimma wannan. Ta hanyar canjin yanayi ne kawai za a iya samun sanyaya kuma a ci gaba da ci gaba.
A halin yanzu, saboda atom ɗin ƙarfe na alkali (kamar Na) yana da electron ɗaya kawai a cikin layin waje, kuma ana iya ɗaukar electrons guda biyu a cikin layin waje na ƙungiyar ƙasa ta alkali (kamar Sr) gaba ɗaya, matakan kuzari na waɗannan atom guda biyu suna da sauƙi, kuma yana da sauƙin cimma "canji mai zagaye", don haka atom ɗin da mutane ke sanyaya yanzu galibi atom ɗin ƙarfe na alkali ne ko atom ɗin ƙasa na alkali.
