Laguerre-Gaussian (LG) beams of various higher-order radial modes are generated by using a reflective phase-only liquid crystal on silicon (LCOS) spatial light modulator (SLM). Because of the LCOS SLM's phase-modulation characteristic of a wide spatial bandwidth, a phase modulation scheme effectively generates higher-order LG beams of up to the fifth-order radial mode. We also perform correlation analyses between the observed and the theoretical two-dimensional mode profiles to universally obtain correlation coefficients of more than 0.946, which suggest mode generations of high quality.
通过使用基于硅的反射型纯相位液晶（LCOS）空间光调制器（SLM）来产生各种高阶径向模式的拉盖尔 - 高斯（LG）光束。由于LCOS SLM具有宽空间带宽的相位调制特性，一种相位调制方案能够有效地产生高达五阶径向模式的高阶LG光束。我们还对观测到的和理论上的二维模式轮廓进行相关性分析，以普遍获得大于0.946的相关系数，这表明高质量的模式生成。
