Abstract: The dependence of the level population on pumping in a boson cascade laser has been theoretically studied. Analytical expressions for the population of various cascade levels and the terahertz mode below and above the pumping threshold are obtained. Formulas for the pumping threshold and external quantum efficiency of the boson cascade laser are derived.
