New phonon lasers can be used in quantum physics

Researchers at the rochester institute of technology (RIT) and the university of rochester have developed a new phonon laser using laser tweezers developed by Nobel laureate Arthur Ashkin, foreign media reported.

The researchers demonstrated a mesoscopic frequency tunable phonon lasaer pointer in which the centre-of-mass oscillations of sio2 nanospheres suspended in a vacuum in optical tweezers. The phonon lasers could be used for single electrons, droplets or even small biological organisms.

In standard optical lasers, the characteristics of the light output are controlled by the material used to produce the laser. But in this phonon laser, the motion of the material particles is controlled by optical feedback. At the same time, this kind of phonon laser can also provide a path for the coherent source of mesoscale phonons, which can be used to solve the basic problems in quantum mechanics and precision measurement applications.

Professor Mishkat Bhattacharya, who is interested in using the device to explore basic quantum physics, said: “we are very excited to see new USES for this device, especially for sensing and information processing, as optical lasers have many applications and are still evolving.
