Abstract

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.
