Abstract
The amplification of light through stimulated emission or nonlinear optical interactions has had a transformative impact on modern science and technology. The amplification of other bosonic excitations, like phonons in solids, is likely to open up new remarkable physical phenomena. This paper reports an experimental demonstration of optical phonon amplification, supported by first-principle calculations. The combination of our experiments and simulations clarifies a microscopic mechanism for phonon-mediated four-wave mixing, a highly interesting process. Our results could be extended toward an enhanced control of phonon-polariton waves, interesting for information transport on subwavelength length scales.
