  • 摘要: 随着水下光通信等应用的兴起,研究光束在海洋湍流中的传输特性尤为重要。为了更贴近实际情况,我们人工搭建了能控制水下湍流强度和盐度的装置来研究涡旋光束和高斯光束在水下湍流中的传输特性。结果表明:相比于未添加海盐的水下湍流,光束在增添海盐的水下湍流中传输光斑会更加弥散,光强会更弱。无论是强湍流还是弱湍流,m=2的涡旋光束在盐度为4.35‰的水下湍流中的闪烁因子都大于其在盐度为2.42‰的水下湍流中所对应的闪烁因子。另外,m=2的涡旋光束传输到相同的距离时,其闪烁因子随着水下湍流的盐度和强度的增大而增大。不同盐度条件下,m=2的涡旋光束的径向闪烁因子随径向距离的增大先减小后增大。另外,我们搭建了另一个可以传输更长距离的实验装置,在20米的传输距离内,拓扑电荷m=2的涡旋光束在的闪烁因子远高于高斯光束所对应的闪烁因子,且m=2的涡旋光束和高斯光束的闪烁因子都随着传输距离的增大而增大。
