Title:
LIGHT AMPLIFIER AND LIGHT AMPLIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/228269
Kind Code:
A1
Abstract:
Provided are a light amplification method and a light amplifier in which: a core that encapsulates luminescence centers is installed and supported, in a rectangular box body having one surface being opened, on upper surfaces of two mutually-facing side walls of the box body that are perpendicular to the open surface, and is made so as to be able to vibrate, thereby constituting a mechanical sympathetic vibration unit; signal light, pump light, and control light that has a difference frequency between the resonance frequency of the luminescence center and the resonance frequency of the mechanical sympathetic vibration unit are made to enter the core, thereby causing the mechanical sympathetic vibration unit to vibrate sympathetically, the signal light, pump light, and control light being the object of amplification; and, due to distortion produced by the mechanical sympathetic vibration, the numerous luminescence centers encapsulated in the core are made to interact with the sympathetic vibration so that, through drawing of the luminescence centers to a prescribed frequency, non-uniform spread of resonant wavelengths of the luminescence centers can be reduced to the width of a single resonance line.
