▎ 摘　　要

NOVELTY - The laser has a graphite nano-belt (3) connected with metal nanowires (5). A first silicon dioxide layer (2), an air groove (6) and a second silicon dioxide layer (4) are connected to a graphene nanometer belt (3). The first silicon dioxide layer and the second silicon dioxide layer are symmetrically located at two sides of the air groove. A gain medium nano-wire (1) is fixed on the first silicon dioxide layer and the second silicon dioxide layer. The gain medium nano-wire is fixedly connected to the graphene nano-meter belt and the air groove. The gain medium nano-wire is formed as an annular or cylindrical, or triangular, square, round, hexagonal, pentagonal, oval and trapezoid-shaped structures. USE - Low threshold surface plasma nanometer laser. ADVANTAGE - The laser has small energy consumption, smaller threshold, ultrafast dynamics process, tunable optical wavelength, smaller size, simple structure and excellent comprehensive performance, and can be realized at room temperature. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a low threshold surface plasma nanometer laser.
