| 英文摘要 | The problem of light localization in two-dimensional random media with different filling densities of the same material particles is studied by use of the finite difference time domain method. Based on the experimental parameters of random media, the spatial distributions of optical field in the media with different filling densities of scattering particles are simulated. Results show that when the scattering mean free path is close to the wavelength, the optical fields are localized obviously in the random media. And with the particle filling density increasing, the localization becomes stronger. So with the same pump beam, it is easier to achieve laser radiation for random media with higher filling densities of scattering particles. The results agree with the experiments qualitatively. |
