| 1 | The band transport model is now a widely accepted photorefractive theory. | |
| 2 | The screen is made from a special photorefractive material. | |
| 3 | This dissertation describes theoretical and experimental research on steady-state photorefractive spatial solitons . | |
| 4 | In this paper, the theoretical analysis of a photorefractive adaptive optical heterodyne detection system is presented for the first time. | |
| 5 | Physical mechanism of the origin of higher order diffraction beams of volume phase grating in photorefractive crystals is explored. |
