EFFICIENT AND DIRECTIONAL NON-RESONANCE LASER USING SCATTERING CAVITY AND MANUFACTURING METHOD THEREOF

Abstract

Various embodiments provide a high-efficiency and directional non-resonant laser using a scattering cavity and a method of manufacturing the same. According to various embodiments, the non-resonant laser may include a gain medium unit in which a scattering cavity and an entrance communicating with the scattering cavity are provided, and a pumping and supply unit configured to supply pumping light to an inside of the scattering cavity. The gain medium unit may be implemented to be excited by the pumping light on the inside of the scattering cavity and to output emission light through the entrance. According to various embodiments, the gain medium unit may weaken the pumping light while reflecting the pumping light on the inside of the scattering cavity, and may amplify the emission light while reflecting the emission light on the inside of the scattering cavity.
