Researchers Invent New Phonon Lasers
According to foreign media reports, researchers from the Rochester Institute of Technology (RIT) and the University of Rochester developed a new type of phonon laser through the laser helium technology invented by Nobel Prize winner Arthur Ashkin.
The silica-based nanospheres suspended in the centroid of the optical tweezers under vacuum, the researchers demonstrated a mesoscopic frequency tunable phonon laser. Such phonon lasers can be used for single electrons, droplets, and even small biological organisms. In standard optical lasers, the characteristics of the light output are controlled by the material from which the laser is produced. In such phonon lasers, however, the motion of the material particles is controlled by optical feedback. Meanwhile, this phonon laser can also provide a path for the coherent source of mesoscale phonons, which can be applied to solve basic problems in quantum mechanics and precision metrology applications.
Professor Mishkat Bhattacharya, who is interested in exploring basic quantum physics using this device, said: "We are very excited to see the new uses of this device, especially for sensing and information processing, because optical lasers are available for various applications and more are still evolving."
Their research was published in Nature Photonics.
