摘要
为了控制2-D Airy光束阵列在焦点的强度,利用高斯光束在频域移动可以进行调控的原理,对其在大气湍流中的效果进行了仿真。结果表明,通过高斯光束在频域的位移,实现了2-D Airy光束阵列焦点处强度从0.85增强到1.1,且操作灵活方便,不需要通过重复编码相位图增加光束数目就可增强光束在焦点的强度;在中等湍流强度下,光束强度可从0.85增强到1.03。该研究对激光在大气中抵抗大气湍流、提高激光通信的质量,具有一定的参考意义。
In order to control the intensity of the 2-D Airy beam array at the focal point,a simulation study was conducted using the principle of modulation of the Gaussian beam moving in the frequency domain.The results show that the intensity enhancement from 0.85 to 1.1 at the focal point of the 2-D Airy beam array is achieved by shifting the Gaussian beam in the frequency domain,and the operation is flexible and convenient without increasing the number of beams by repeatedly encoding the phase diaphragm to enhance the intensity of the beam at the focal point,and its effect in atmospheric turbulence is simulated,beam intensity enhancement from 0.85 to 1.03 at moderate turbulence intensity.The modulation is of research significance for the laser to resist atmospheric turbulence in the atmosphere and improve the quality of laser communication.
