Isimiso sokupholisa nge-laser kanye nokusetshenziswa kwayo kuma-athomu abandayo
Ku-athomu ebandayo, umsebenzi omningi wokuhlola udinga ukulawula izinhlayiya (ukubopha ama-athomu e-ionic, njengewashi le-athomu), ukuzinciphisa, nokuthuthukisa ukunemba kokulinganisa. Ngokuthuthuka kobuchwepheshe be-laser, ukupholisa nge-laser nakho sekuqalile ukusetshenziswa kabanzi kuma-athomu abandayo.
Esikalini se-athomu, ingqikithi yokushisa yijubane lapho izinhlayiya zihamba khona. Ukupholisa nge-laser ukusetshenziswa kwama-photon nama-athomu ukushintshanisa umfutho, ngaleyo ndlela kupholise ama-athomu. Isibonelo, uma i-athomu inejubane eliya phambili, bese imunca i-photon endizayo ehamba ngakolunye uhlangothi, khona-ke ijubane layo lizoncipha. Lokhu kufana nebhola eligingqika phambili otshanini, uma lingacindezelwa ngamanye amandla, lizoma ngenxa “yokumelana” okubangelwa ukuthintana notshani.
Lokhu ukupholisa kwama-athomu nge-laser, futhi inqubo iyimjikelezo. Futhi kungenxa yalo mjikelezo ukuthi ama-athomu aqhubeka ephola.
Kulokhu, ukupholisa okulula kakhulu ukusebenzisa umphumela we-Doppler.
Kodwa-ke, akuwona wonke ama-athomu angapholiswa ngama-laser, futhi "ushintsho olujikelezayo" kumele lutholakale phakathi kwamazinga e-athomu ukuze kufezwe lokhu. Ukupholisa kungafinyelelwa futhi kuqhubeke ngokuqhubekayo kuphela ngoshintsho olujikelezayo.
Njengamanje, ngenxa yokuthi i-athomu yensimbi ye-alkali (njenge-Na) ine-electron eyodwa kuphela ongqimbeni lwangaphandle, kanti ama-electron amabili ongqimbeni lwangaphandle lweqembu lomhlaba we-alkali (njenge-Sr) nawo angabhekwa njengawo wonke, amazinga wamandla ala ma-athomu amabili alula kakhulu, futhi kulula ukufeza "ushintsho olujikelezayo", ngakho-ke ama-athomu apholile manje ngabantu ikakhulukazi ama-athomu ensimbi ye-alkali alula noma ama-athomu omhlaba we-alkali.
