将衍射光学元件写入空间光调制器，实验获得了规则三尖光束。它们的传播特性和拓扑结构进行了研究。实验结果表明，光学规则三尖光束的每个尖点与艾里光束的主瓣相似，在自由空间中沿沿着曲线路径传输，因而具有“横向加速”特性。此外，我们还从实验上证明了光学规则三尖点光束可以抵抗局部畸变变形。因此，这种光束可以应用在恶劣的光学环境中，例如作为探测微观世界的探针，以及作为研究高场激光与物质相互作用的能源。(C)2012美国光学学会
By using the diffractive optical elements written onto a spatial light modulator, we experimentally obtain optical regular triple-cusp beams. Their propagation characteristics and topological structures are subsequently investigated. The experimental results demonstrate that each cusp of an optical regular triple-cusp beam, similar to the main lobe of an Airy beam, propagates along curved paths in free space, hence tends to adopt the "transverse acceleration" property. Moreover, we experimentally prove that optical regular triple-cusp beams can resist local distorted deformation. Such beams can thus be applied in adverse optical environments, such as a probe for the exploration of microscopic world and as an energy source for research on high-field laser-matter interactions.
