Abstract

Stimulated emission has been obtained from intra-center donor transitions in silicon monocrystals doped by arsenic. The Si:As laser was optically excited by radiation from a CO<sub>2</sub> laser. The emission spectrum consists of two lines corresponding to the 2p<sub>±</sub>-->1s(E) and 2p<sub>±</sub>-->1s(T<sub>2</sub>) intra-center arcenic transitions. The population inversion is formed due to fast 2s-->1s(A<sub>1</sub>) electron relaxation assisted by intervalley longitudinal acoustic f-phonon emission. This keeps the excited donor states below the 2p<sub>±</sub> state unpopulated. Thus population inversion occurs between the 2p<sub>±</sub> state and the 1s(E), 1s(T<sub>2</sub>) states.
