Phonon optical grating used for superconductivity dielectric resonant cavity phonon laser device

Abstract

Provided is a phonon optical grating used for a superconductivity dielectric resonant cavity phonon laser device. The phonon optical grating comprises a buffer layer (1), a dielectric layer (2), an impurity layer (3), another dielectric layer (4) and another buffer layer (5), wherein the buffer layer (1) and the buffer layer (5) are arranged to enable the phonon optical grating to be matched with the size of a gap of the phonon laser device when the phonon optical grating is embedded in the emitting end of the superconductivity dielectric resonant cavity phonon laser device and to prevent the dielectric layer (2) and the dielectric layer (4) from being abraded, the dielectric layer (2) and the dielectric layer (4) are composed of two different materials in an alternately repeated mode, the impurity layer (3) is arranged between the dielectric layer (2) and the dielectric layer (4), and the dielectric layer (2), the impurity layer (3) and the dielectric layer (4) are in axial symmetry on the whole.

Description

technical field [0001] The invention relates to a phonon grating, which is mainly used in a superconducting medium resonant cavity phonon laser to achieve the purpose of modulating the phonon laser, and relates to the technical field of phonon transmission. Background technique [0002] In June 2009, scientists from the University of Nottingham in the United Kingdom (The University of Nottingham) collaborated with colleagues from Ukraine to develop a new type of acoustic laser device and named it a phonon laser [3]. ), while the phonon laser is formed by the phonon vibrating by the sound wave. It is a laser in the acoustic sense, and strictly speaking, it should be called "exciting sound". The invention of phonon lasers has attracted the attention of many scientists, who believe that phonon lasers will have broad application prospects in the fields of computer computing, medical imaging and anti-terrorism security inspection.
