Sound amplification by stimulated emission of radiation
SASER is a device capable of emitting acoustic radiation. By focusing and controlling the sound waves, it enables us to utilise them as accurate and high-speed carriers of information in many kinds of applications, similar to the use of light emitted by laser.Acoustic radiation (sound waves) can be emitted by using the process of sound amplification based on stimulated emission of phonons. Sound (or lattice vibration) can be described by a phonon just as light can be considered as photons, and therefore one can state that SASER is the acoustic analogue of the laser.In a SASER device, a source (e.g. an electric field as a pump) produces sound waves (lattice vibrations, phonons) which travel through an active medium. In this active medium, a stimulated emission of phonons leads to amplification of the sound waves, resulting in a sound beam coming out of the device. The sound wave beams emitted from such devices are highly coherent.The first successful SASERs were developed in 2010.
