We investigate theoretically and observe experimentally a continuously tuning distorted Airy-like beam, which is generated by introducing a controllable rotation angle into the phase patterns. The beam wavefront can be tuned flexibly by using the introduced angle. The main lobes of beams can be controlled readily to propagate along specified parabolic trajectories. The relevant optical behaviors are discussed and demonstrated in detail. The experimental results are in good agreement with the theoretical analysis. The intriguing characteristics of the continuously tuning Airy-like beams could provide more degrees of freedom in cell and atom manipulation.
我们从理论上进行了研究,并通过实验观察到一种连续调谐的类艾里畸变光束,它是通过在相位图案中引入可控旋转角度而产生的。利用引入的角度可以灵活地调谐光束波前。光束的主瓣可以很容易地控制沿着指定的抛物线轨迹传播。详细讨论并展示了相关的光学行为。实验结果与理论分析吻合良好。连续调谐类艾里光束的有趣特性可以在细胞和原子操纵中提供更多的自由度。
