Abstract
A surface plasmon infrared nano-pulse laser having a multi-resonance competition mechanism, consisting of the four parts of a surface plasmon nano-pin resonance chamber (1), a spacer layer (2), a gain medium (3), and a two-dimensional material layer (4). The surface plasmon nano-pin resonance chamber (1) consists of a metal nano rod (11) and one or more nano sheets (12) grown thereon, the surface plasmon nano-pin resonance chamber (1) and the gain medium (3) being isolated by the isolating layer (2), and the two-dimensional material layer (4) covering a surface of the surface plasmon nano-pulse laser; positive and negative electrodes (5) are located at two ends of the surface plasmon nano-pulse laser, and a layer of a two-dimensional material having a feature of saturatable absorption is introduced to a surface of the nano-pin resonance chamber.
