The observation of the stimulated terahertz radiation in magnetic junctions at the room temperature resulting from the current injection of nonequilibrium spins is reported. Contacts between two ferromagnetic layers and between a ferromagnetic and an antiferromagnetic layer are investigated.

Stimulated emission is formulated in completely classical terms and is shown to occur in general only in nonlinear systems. Our approach is based on the frequency-dependent susceptibility, which in both the classical and quantum-mechanical descriptions is the main characteristic determining whether there is absorption or stimulated emission.

Stimulating the emission of money
2005Abstract TRG’S LIMITED RESOURCES kept Gould a few steps behind Bell Labs. TRG was a small military contractor; it didn’t have piles of money from one of the world’s largest corporations to invest in research. TRG’s research money came from military agencies, and finding the right agency to foot the bill was always a challenge.

Stimulated Emission of Bremsstrahlung
Bell System Technical Journal, 1962A formula for the probability of stimulated emission of Bremsstrahlung is derived. It is shown that stimulated emission occurs if the incident electrons travel in a direction roughly parallel to the electric field vector of the wave stimulating the emission. Emission from free electrons is used in electron tube devices.

Two methods to achieve a stimulated emission of phonons with frequencies in the THz-regime are described here. In both cases the generation of phonons is achieved by coupling to electronic states in doped dielectric crystals. The impurity ions are excited by pulsed laser light and an almost complete conversion of the absorbed energy is obtained ...
