Isimiso sokupholisa i-laser kanye nokusetshenziswa kwayo kuma-athomu abandayo
Ku-athomu ebandayo ye-athomu, umsebenzi omningi wokuhlola udinga ukulawula izinhlayiya (ukubopha ama-athomu e-ionic, njengamawashi e-athomu), ukuwanciphisa, nokuthuthukisa ukunemba kokulinganisa.Ngokuthuthuka kobuchwepheshe be-laser, ukupholisa nge-laser nakho sekuqalile ukusetshenziswa kabanzi kuma-athomu abandayo.
Esikalini se-athomu, ingqikithi yezinga lokushisa ijubane izinhlayiya ezihamba ngalo.Ukupholisa i-laser ukusetshenziswa kwama-photon nama-athomu ukushintshanisa umfutho, ngaleyo ndlela apholise ama-athomu.Isibonelo, uma i-athomu inejubane eliya phambili, bese idonsa i-photon endizayo ehamba kwelinye icala, khona-ke isivinini sayo sizokwehla.Lokhu kufana nebhola eligingqika phambili otshanini, uma lingaphushwa ngamanye amandla, liyoma ngenxa “yokumelana” okulethwa wukuthintana notshani.
Lokhu ukupholisa nge-laser kwama-athomu, futhi inqubo iwumjikelezo.Futhi kungenxa yalo mjikelezo ukuthi ama-athomu alokhu ephola phansi.
Kulokhu, ukupholisa okulula ukusebenzisa umphumela we-Doppler.
Nokho, akuwona wonke ama-athomu angapholiswa ngamalaser, futhi “uguquko lwe-cyclic” kufanele lutholakale phakathi kwamazinga e-athomu ukuze kuzuzwe lokhu.Kuphela ngokusebenzisa izinguquko ezijikelezayo lapho ukupholisa kungafinyelelwa futhi kuqhubeke ngokuqhubekayo.
Njengamanje, ngenxa yokuthi i-athomu yensimbi ye-alkali (njenge-Na) ine-electron eyodwa kuphela ungqimba olungaphandle, futhi ama-electron amabili ongqimba olungaphandle lweqembu lomhlaba we-alkali (njenge-Sr) nawo angabhekwa njengawo wonke, amandla. amazinga alawa ma-athomu amabili alula kakhulu, futhi kulula ukufinyelela "inguquko ye-cyclic", ngakho-ke ama-athomu manje asepholiswe abantu ngokuvamile ama-athomu ensimbi ye-alkali alula noma ama-athomu e-alkali yomhlaba.
