A team of researchers from Tsinghua University have achieved phonon and photon lasing in a silicon-based optomechanical crystal cavity. This paves the way for the harnessing of the coherence of ...

The direct lasing outside the fluorescence spectrum is deemed impossible owing to the ‘zero-gain’ cross-section. However, when electron-phonon coupling meets laser oscillation, an energy ...

"Think of phonon lasing as a counterpart to traditional optic, or photon lasing, with exciting applications in medical surgery, materials science and communications.

Quantum leap for phonon lasers Date: February 24, 2010 Source: American Physical Society Summary: Physicists have taken major step forward in the development of practical phonon lasers, which emit ...

Posted: Oct 28, 2015: A new physical mechanism allows 'phonon lasing' driven by optical forces at ambient conditions (Nanowerk News) Last years have witnessed a steady and fast increase in the number ...

Lasing Beyond Light. Physicists focus on whole new types of waves, ... And phonon lasers vault the technology out of the electro­magnetic spectrum altogether, creating coherent beams of sound.

At a threshold pump power, phonon gain exceeds phonon loss resulting in phonon lasing. (Bottom) Phonon amplification in a superlattice. Tunneling of electrons from one quantum well to the next is ...

This study addresses these gaps by investigating the mechanisms behind pulse doubling in perovskite nanowires. The Current Study . The quasi-2D perovskite nanowires were synthesized using a ...
