Ihame ryo gukonjesha laser no kuyikoresha kuri atome ikonje

Muri fiziki ya atome ikonje, imirimo myinshi yubushakashatsi isaba kugenzura ibice (gufunga atome ionic, nkamasaha ya atome), kubitindaho, no kunoza neza ibipimo.Hamwe niterambere ryikoranabuhanga rya laser, gukonjesha laser nabyo byatangiye gukoreshwa cyane muri atome ikonje.

Ku gipimo cya atome, ishingiro ry'ubushyuhe ni umuvuduko ibice bigenda.Gukonjesha Laser ni ugukoresha fotone na atome kugirango uhindure imbaraga, bityo gukonjesha atome.Kurugero, niba atome ifite umuvuduko wimbere, hanyuma igakurura fotone iguruka igenda itandukanye, noneho umuvuduko wacyo uzatinda.Ibi ni nkumupira uzunguruka imbere yibyatsi, niba udasunitswe nizindi mbaraga, bizahagarara kubera "resistance" yazanywe no guhura nibyatsi.

Ubu ni laser yo gukonjesha atome, kandi inzira ni cycle.Kandi kubera iyi nzinguzingo atome ikomeza gukonja.

Muri ibi, gukonjesha byoroshye ni ugukoresha ingaruka ya Doppler.

Ariko, ntabwo atome zose zishobora gukonjeshwa na laseri, kandi "inzibacyuho ya cycle" igomba kuboneka hagati yurwego rwa atome kugirango ubigereho.Gusa binyuze mubyerekezo byinzibacyuho birashobora gukonja kugerwaho no gukomeza ubudahwema.

Kugeza ubu, kubera ko atome ya alkali (nka Na) ifite electron imwe gusa murwego rwo hanze, kandi electroni ebyiri murwego rwo hanze rwitsinda ryisi ya alkali (nka Sr) nayo ishobora gufatwa nkibintu byose, ingufu urwego rwizi atome zombi ziroroshye cyane, kandi biroroshye kugera kuri "cycle cycle", bityo atom ubu ikonjeshwa nabantu usanga ahanini ari ibyuma byoroshye bya alkali cyangwa atome yisi ya alkali.
