| 摘 要： | 在BaTiO3:Ce晶体上,用两He-Ne激光为模拟光源,进行远场自泵浦相位共轭.通过研究不同入射强度比的两种光产生的相位共轭光强变化,特别是它们各自建立相位共轭光栅的响应时间差别,发现非单一强度分布的远场光产生的相位共轭光在时序上能分离.依此特性,初步探索不配合目标的信标光成为点光源用于自适应光学系统的问题.

| Abstract: | Two He-Ne lasers in the far field acted as simulated light sources carried out self-pumped phase conjugation in BaTiO3:Ce crystal. By studying the changes of their conjugate intensity, especially the response time differences of their grating build-up with different incident light intensities, it was found that the conjugate light produced by the non-single intensity distribution light in far field can be separated in time sequence. With these specific properties, the problem of how to make the beacon light on a uncooperative target become a light spot used for an adaptive optical system may be dealt with tentatively. |
