"UkuPola" luphawu oluqhelekileyo lweendlela ezahlukeneyo zokuhamba, ezigqitywe ngumgaqo wokwenziwa kwe-laser. II-Laser Beamiveliswa yimitha evunyiweyo ye-therium ekhuphayo ekhupha amasuntswana aphakathi ngaphakathii-laser. I-radiation evunyiweyo inomlinganiswa ophawulekayo: Xa iphoton yangaphandle ibeka isuntswana eliphezulu, isuntswana liyayicaphukisa i-photon kunye notohali ukuya kwinqanaba lamandla asezantsi. Iifoto eziveliswe kule nkqubo zinesigaba esifanayo, isikhokelo esifanayo kunye nemeko yokugcwala njengeefoto zangaphandle. Xa i-Photon Sumam yenziwa kwi-laser, zonke iifoto kwi-Photon Syam Yabelana ngeSigaba esifanayo, isikhokelo se-Propathiation, kunye neLizwe lokuSebenza. Ke ngoko, i-laser ye-laser ye-laser (i-frequency) kufuneka ityhutywe.
Ayizizo zonke iinqobo zokuhamba ziphangiwe. Imeko yokugcwalisa i-laser ichatshazelwe zizinto ezininzi, kubandakanya:
1. Ukucingisisa i-resonator: Ukuze kuqinisekiswe ukuba iifoto ezininzi zisekelwe ukwenza izithembiso ezizinzileyo kwi-cavity kwaye iveliseukukhanya kwe-laser. Ngokutsho komthetho we-fresnel, isenzo sefilimu ye-filtilayer ibangela ukukhanya okumiselweyo kokutshintsha ukusuka ekukhanyeni kwendalo ukuya kutshoUkukhanya kwento.
2. Iimpawu ze-zuza yendawo: Isizukulwane se-laser sisekwe kwimitha enyanzelisiweyo. Xa ii-atom ezinemincili ze-datom i-datoneyitha phantsi kocwecwe zemifanekiso yasemkhosini, ezi foto zishukumisa kwicala elinye (imeko yepoliza) njengeefoto zangaphandle, zivumela i-laser yendalo. Nokuba utshintsho oluncinci lwelizwe lokulimala luya kuncitshiswa nguRemonator kuba izithembiso ezizinzileyo azinakubekwa.
Eyona nkqubo yokwenziwa kwe-laser ye-laser, iplate ye-wave kunye ne-crystal ye-polarial zihlala zongezwa ngaphakathi kwi-laser ukuze ilungiselele imeko yoziziselo yendawo yothando, ukuze imeko yepolizac kwi-cavity yahlukile. Oku kungekuphela nje ukuba amandla aseleyo agxile ngakumbi, ukulungisa ukusebenza kakuhle kuyaphakama, kodwa kukuphepha ilahleko kubangelwe kukungakwazi ukwenza i-oscillate. Ke ngoko, imeko yokulinganisa yase-laser ixhomekeke kwizinto ezininzi ezinje ngolwakhiwo, uhlobo lwemeko ye-zuza kunye neemeko ze-oscicicloll, kwaye azisoloko zahlukile.
