- Scientists in China have created an unprecedentedly bright laser that shoots particles of sound instead of light.
- This is the most powerful "sound laser" yet.
- Unlike regular lasers, that emit light particles called photons, these machines release particle-like chunks of sounds called phonons.
- The output is similar - the particles are released in a narrow beam, like optical lasers emit photons.
- Phonons are less affected while moving through liquids, and can be more effective in imaging watery tissues and deep-monitoring.
- Since they can emit sound in the terahertz frequency range, the beam can also be used in airport scans.
