We report on a simple experimental scheme based on a pair of cylindrical lenses (convex and concave) of the same focal length and common optical elements, producing high power optical beams in 1D and/or 2D Airy intensity profiles with laser polarization as the control parameter. Using an ultrafast Yb-fiber laser at 1064 nm of average power of 5 W in a Gaussian spatial profile and pulse width of $\sim 180\mathrm{fs}$, we have generated 1D and 2D Airy beams at an efficiency of 80% and 70%, respectively, and a pulse width of $\sim 188$ and $\sim 190\mathrm{fs}$, respectively. We have measured the transverse deflection rate of 1D and 2D beams to be $\sim 5.0\times {10}^{-5}$ 1/mm and $\sim 2.0\times {10}^{-5}$ 1/mm, respectively. Simply rotating the polarization state of the 1D cubic phase modulated beam in the experiment, we can produce 1D and 2D Airy beams on demand. Using a 5 mm long bismuth borate (${\mathrm{BiB}}_3{\mathrm{O}}_6$), we have also studied frequency-doubling characteristics of both 1D and 2D Airy beams. Like the 2D Airy beam, the 1D Airy beam also produces a frequency-doubled 1D Airy and an additional 1D spatial cubic structure. Like the Gaussian beams, we have observed the focusing dependence of conversion efficiency for both 1D and 2D Airy beams, producing green 1D and 2D Airy beams of output powers in excess of 110 and 150 mW for 3.4 and 2.8 W of fundamental power, respectively.

同时产生大功率，超快的1D和2D Airy光束及其倍频特性

我们报告了一个简单的实验方案，该方案基于一对具有相同焦距和常见光学元件的圆柱透镜（凸和凹），以激光偏振为控制参数，以一维和/或二维艾里强度剖面产生高功率光束。在高斯空间分布中使用平均功率为5 W的1064 nm超快Yb光纤激光器，脉冲宽度为$〜180\mathrm{fs}$，我们分别以80％和70％的效率产生了一维和二维艾里光束，脉冲宽度为 $〜188$ 和 $〜190\mathrm{fs}$， 分别。我们已经测量了1D和2D光束的横向偏转速率为$〜5.0\times {10}^{-5}$ 1 / mm和 $〜2.0\times {10}^{-5}$1 / mm。在实验中只需旋转一维立方相位调制光束的偏振态，我们就可以按需产生一维和二维艾里光束。使用5毫米长的硼酸铋（${\mathrm{围兜}}_3{\mathrm{Ø}}_6$），我们还研究了1D和2D艾里光束的倍频特性。与2D Airy光束一样，1D Airy光束也产生倍频的1D Airy和附加的1D空间立方结构。像高斯光束一样，我们已经观察到1D和2D艾里光束的转换效率的聚焦依赖性，对于3.4 W和2.8 W基本功率，分别产生超过110和150 mW的绿色1D和2D艾里光束。
