Time broj atoma u pobuđenom stanju N2 postaje veći od broja atoma u nepobuđenom stanju N1, što se naziva inverzija napučenosti ili inverzija populacije. Za prijelaz u pobuđeno stanje fizikalno je nevažno kojim je putem i načinom dovedena energija, dok kod prijelaza iz pobuđenog u nepobuđeno stanje nastaje kvantni skok, to jest emisija fotona kojima energija odgovara razlici energetskih razina. Općenito vrijedi Boltzmannov zakon:
