利用拉盖尔高斯涡旋光束的共轴叠加，研究2×2光环晶格阵列的产生方法。从理论上分析了光环晶格阵列的形成与分布特征，并利用数值计算得出了光环晶格阵列。通过共轭对称延拓傅里叶计算全息生成了光环晶格阵列的全息图，基于反射式空间光调制器的光电实验产生了与理论一致的光环晶格阵列。光环晶格阵列具有更多的控制参数和更复杂的光束分布特征，为光束的原子操控研究提供了一定的理论和实验依据。

A method for the generation of 2×2 optical ring lattice array by coaxial superposition of Laguerre-Gaussian beams is proposed. The formation and distribution characteristics of optical ring lattice array are discussed in theory, then optical ring lattice array is produced by numerical calculation. The hologram of optical ring lattice array is generated by conjugate-symmetric extension based Fourier computer-generated holography, and the optical ring lattice array is experimentally produced based on a reflected-type spatial light modulator. Excellent agreements between theoretical and experimental results are observed. Optical ring lattice array provides more controllable parameters and more complicated light distributions, so the research results provide some theoretical and experimental foundations for atom trapping of light beams.
