| 英文摘要 | self-focusing is a well-researched phenomenon. nanoscale spots can be achieved through self-focusing, which is an alternative method for achieving high-density data storage, high-resolution light imaging, and maskless nanolithography. several research groups have observed that self-focusing spots can be reduced to nanoscale levels via incident laser power manipulation. self-focusing spots can be analyzed by solving the nonlinear schrodinger equation and the finite difference time domain method. however, both procedures are complex and time-consuming. in the present work, a multilayer thin-lens self-focusing model that considers diffraction effects and changes of refractive index along the radial and film thickness directions is proposed to analyze the self-focusing behavior and traveling process of light beams intuitively. the self-focusing behaviors of as2s3 are simulated, and results show that a nanoscale self-focusing spot with a radius of about 0. 12 mu m can be formed at the bottom of nonlinear sample when the incident laser power exceeds 4.25 mw. our findings are basically consistent with experimental reports and provide a good method for analyzing and understanding the self-focusing process. an appropriate application schematic design is also provided.
