| Popis: | Self-diffraction appears when the strong laser goes through two-dimensional material suspension, and this spatial self-phase modulation (SPPM) phenomenon can be used to measure nonlinear optical parameters and achieve optical switch. At present, the mechanism of SPPM is still ambiguous. The debate mainly focuses on whether the phenomenon is caused by the nonlinear refractive index of the two-dimensional material or the thermal effect of the laser. The lack of theory limits the dimension of the phase modulation to the radius of the diffraction ring and the vertical imbalance. Therefore, it is urgent to establish a unified and universal SSPM theoretical system of two-dimensional material. |
