Abstract

The invention provides a design method of a plasma laser device. The design method of the plasma laser device comprises the following steps that a required laser wavelength is obtained; the size and base gains of cross-shaped metal structures on a laser device base are obtained according to a corresponding relationship between the laser wavelength and the sizes of base gains and the cross-shaped metal structures on the base; and the laser device comprises a tetramer composed of the four cross-shaped metal structures, and the tetramer is arranged on the base. According to the technical scheme,the sizes of the cross-shaped metal structures on the required laser device base are obtained according to the corresponding relationship between the laser wavelength and the sizes of the cross-shapedmetal structures on the base, thus, the sizes of the cross-shaped metal structures on the required laser device base can be obtained, the design method is simple, and the problem that in the prior art, the method of designing the plasma laser device according to the wavelength is relatively complex is solved.

Description

technical field [0001] The invention belongs to the technical field of plasma lasers, and in particular relates to a design method of a plasma laser. technical background [0002] Laser has always played an important role in science and technology, with the development of modern technology, miniaturization (such as nanometer size) is an inevitable requirement, but due to the physical size and working principle, traditional lasers cannot break the diffraction limit so they cannot meet this request. [0003] In 2003, Bergman et al. proposed the concept of Surface Plasmon Stimulated Radiation Amplification (SPASER), using the properties of localized surface plasmon resonance (LSPR) radiation amplification generated by the interaction between metal nanostructures and their surrounding gain materials. The work of a new type of nano-laser is demonstrated and its working principle is demonstrated. With the advancement of research, more and more types of plasmonic lasers have appe...
