Document Type and Number:
WIPO Patent Application WO/2022/131643
Kind Code:
A1
Abstract:
Various embodiments provide a high-efficiency directional non-resonant laser using a scatter cavity, and a manufacturing method therefor. According to various embodiments, a non-resonant laser comprises: a gain medium unit in which a scatter cavity and an entrance communicating with the scatter cavity are provided; and a pumping light supply unit for supplying pumping light to the inside of the scatter cavity, wherein the gain medium unit can be implemented so as to be excited by means of the pumping light inside the scatter cavity, thereby outputting emission light through the entrance. According to various embodiments, the gain medium unit can attenuate the pumping light while reflecting the pumping light inside the scatter cavity, and amplify the emission light while reflecting the emission light inside the scatter cavity.
