We demonstrate both experimentally and theoretically controlled acceleration of one- and two-dimensional Airy beams in optically induced refractive-index potentials. Enhancement as well as reduction of beam acceleration are realized by changing the index gradient, while the beam shape is maintained during propagation through the linear optical potential. Our results of active acceleration manipulation in graded media are pertinent to Airy-type beam propagation in various environments.
我们通过实验和理论证明了在光诱导折射率势中对一维和二维 Airy 光束的控制加速。通过改变折射率梯度，可以实现光束加速的增强和减弱，同时在通过线性光学势传播时保持光束形状。我们在梯度介质中对光束加速的主动操控结果与各种环境中 Airy 型光束的传播有关。
