Sound amplification by stimulated emission of radiation of a coherent amplification of THz sound. The THz stimulated phonon induced transitions between the electron superlattice states lead to this coherent amplification while processing a population inversion. An essential step towards coherent generation ("sasing") of THz sound and other active hypersound devices has been provided by this achievement of THz sound amplification. Generally, in a device where the threshold for "sasing" is achieved, the technique described by this proposed scheme could be used to measure the coherence time of the emitted hypersound. Sound amplification by stimulated emission of radiation Sound amplification by stimulated emission of radiation (SASER) refers to
Primetime Emmy Award for Outstanding Art Direction for a Miniseries or Movie Direction for a Miniseries or Movie Primetime Emmy Award for Outstanding Art Direction for a Miniseries or Movie The Primetime Emmy Award for Outstanding Art Direction for a Miniseries or Movie is a retired award that was handed out annually at the Creative Arts Emmy Awards. In 2014, the category was restructured into Outstanding Production Design for a Narrative Contemporary or Fantasy Program (One Hour or More) and Outstanding Production Design for a Narrative Period Program (One Hour or More).
