| 摘 要： | 拉盖尔-高斯（Laguerre-Gaussian，LG）模是光子的轨道角动量本征态，它在未来的光镊、量子信息和计算等领域有潜在的应用价值。分别用两种记录介质-全息干板和喷墨透明胶片-制作了全息光栅。通过这种全息光栅在实验上产生了拓扑数从一阶到高阶的拉盖尔-高斯模，同时观察到高阶模的空间不稳定特性。并且详细讨论了光栅制作过程中的各种控制参量如曝光时间及强度对光栅衍射效率的影响。

| Abstract: | Laguerre-Gaussian (LG) mode is the eigen-state of the orbital angular momentum of photon.It has potential applications in the fields of optical tweezer,quantum information process and computation.Two kinds of recording mediumsholographic plate and ink-jet transparent film are used to manufacture the holographic grating.Laguerre-Gaussian (LG) modes with topological indices from the first order to high order have been observed in the experiment.It is also noticed the high order modes are spatial unstable.Furthermore,the related controlling parameters,such as the exposure time and intensity which influence the diffraction efficiency,are discussed in detail. |
