Observation of Coherent Acoustic Phonon Lasing in InGaN/GaN MQWs

Not Accessible

Your library or personal account may give you access


One of the most desirable properties of phonon system is sound amplification by stimulated emission of phonon radiation, coined as SASER or called "phonon laser" or "acoustic laser", which is the acoustic counterpart of LASER. Phonon stimulated emission, or sound amplification, has been previously observed for several occasions1,2 in extremely low temperatures, however a "lasing" behavior of the phonon oscillators has never been establishei.
