Abstract
An apparatus and methods for an optically pumped laser that has a cascade of light-emitting interband transitions are disclosed. The apparatus disclosed contains multistep interband cascade regions able to generate a plurality of photons for a pump photon absorbed from an optical pump source. The methods disclosed teach how to produce a plurality of photons for a pump photon absorbed from an optical pump source.
