Kwinyani, i-laser Pumpting yinkqubo yokuphumelela iphakathi yokufezekisa imeko apho inokuphuma khona. Oku kwenziwa ngokuqhelekileyo ngokufaka ukukhanya okanye umbane okwangoku kwi-methom, kuchulumancisa iiathom zayo kunye nokukhokelela ekukhanyeni komntu. Le nkqubo isisiseko ivele ikakhulu ukusukela ekwenzeni ii-larsers zokuqala phakathi kwenkulungwane yama-20.
Ngelixa idla ngokuhlala ngokulinganayo ngokulinganayo, impompo ye-laser isebenzisa inkqubo ye-Quagu. Kubandakanya ukusebenzisana okuntsonkothileyo phakathi kweefoto kunye ne-atomic okanye ubume bemolekyuli bendawo yokufumana. Iimodeli eziphambili zithathele ingqalelo i-phenomena njengeyona ndawo ye-rabi, ebonelela ngokuqonda ngakumbi kolu nxibelelwano.
I-Laser Pumpy yinkqubo apho amandla, ngokwesiqhelo ngohlobo lokukhanya okanye ngombane, inikezelwa kwi-laser yendawo yokufumana i-laser ukuphakamisa iiathom zayo okanye iimolekyuli zayo. Olu tshintsho lwamandla lubalulekile ekufezekiseni indawo yokuhlala abantu, ilizwe elingaphezulu apho amasuntswana anoyolo kunendawo engezantsi yamandla, evumela i-ofisi yendlela yokukhanyisa ukuphakanyiswa. Inkqubo ibandakanya ukusebenzisana kobungakanani obunzima, ihlala imodareyithiwe ngokusebenzisa i-equations yereyithi okanye imikhamo yoomatshini abaphambili. Imicimbi ephambili ibandakanya ukhetho lomthombo wempompo (njenge-larser theds okanye i-pumpt ye-gemporives), kunye nokuphelisa impompo, i-polariment, i-polarization) yokutshatisa iimfuno ezithile ze-zuza. I-laser Pumpting ibalulekile kwiintlobo ezahlukeneyo ze-laser, kubandakanya urhulumente oqinileyo, i-semiconductor, kunye ne-igesi i-laser, kwaye ibalulekile ekusebenzeni kakuhle nasekusebenzeni kakuhle.
