Inkoranyabumenyi nto: Ihame ryo gusudira hakoreshejwe laser n'uburyo bwo kuyikoresha
Urwego rw'ingufu
Ibintu bigizwe na atome, naho atome zigizwe na nucleus na electron. Electron zizenguruka nucleus. Ingufu za electron muri atome si ukwifata.
Mechanic ya Quantum, isobanura isi ya mikorosikopi, itubwira ko electron zigira ingufu zidahinduka. Ingufu zitandukanye zijyanye n'ingufu zitandukanye za electron: inzira zizenguruka kure y'umubumbe w'isi zigira ingufu nyinshi.
Byongeye kandi, buri murongo ushobora gufata umubare ntarengwa wa electron. Urugero, umurongo wo hasi cyane (wegereye nucleus) ushobora gufata electron 2, mu gihe inzira zo hejuru zishobora gufata electron 8, n'ibindi.
Impinduka
Elektronike zishobora kuva ku rwego rumwe rw'ingufu zijya ku rundi binyuze mu kwinjiza cyangwa kurekura ingufu.
Urugero, iyo electron yinjije fotoni, ishobora gusimbuka iva ku rwego rwo hasi rw'ingufu ikagera ku rwego rwo hejuru. Mu buryo nk'ubwo, electron iri ku rwego rwo hejuru rw'ingufu ishobora kumanuka ikagera ku rwego rwo hasi isohora fotoni.
Muri izi nzira, ingufu za fotoni ikoreshwa cyangwa isohoka buri gihe zingana n'itandukaniro ry'ingufu ziri hagati y'urwego rwombi. Kubera ko ingufu za fotoni zigena uburebure bw'urumuri, urumuri rukoreshwa cyangwa rusohoka rufite ibara rihoraho.
Ihame ryo gukora laser
Gukurura Ibinure Bikangurirwa
Gukurura ibintu bibaho iyo atome ziri mu rwego rwo hasi rw’ingufu zifata imirasire yo hanze hanyuma zigahinduka mu rwego rwo hejuru rw’ingufu. Electron zishobora gusimbuka ziva ku rwego rwo hasi zikagera ku rwego rwo hejuru zifata fotoni.
Imyuka iva mu mubiri itera umwuka
Ibyuka bivangwa bivuze ko electron ziri ku rwego rwo hejuru rw'ingufu, munsi y' "gukangura" cyangwa "gutera" fotoni, zihinduka zikajya ku rwego rwo hasi rw'ingufu hanyuma zigasohora fotoni ifite inshuro imwe n'iyo fotoni y'impanuka.
Ikintu cy'ingenzi mu gusohora imyuka ishyushye ni uko fotoni ikorwa isa n'iya mbere: inshuro imwe, icyerekezo kimwe, kandi ntaho itandukaniye na gato. Muri ubu buryo, fotoni imwe iba fotoni ebyiri zisa binyuze mu nzira imwe yo gusohora imyuka ishyushye. Ibi bivuze ko urumuri rukomezwa cyangwa rwongerwa - ihame ry'ibanze ryo gukora laser.
Ibyuka biva mu kirere mu buryo butunguranye
Ibyuka bitunguranye bibaho iyo electron ziri ku rwego rwo hejuru rw'ingufu zimanuka zikagera ku rwego rwo hasi nta ngaruka zo hanze, zigatanga urumuri (imirasire ya electromagnetique) mu gihe cy'impinduka. Ingufu za fotoni ni E=E2−E1, itandukaniro ry'ingufu hagati y'urwego rwombi.
