| Non-diffracting beam having a high concentration of light intensity,the small diameter of center spot,the ability of long range propagation,and it is applied in the field of energy transfer between spacecraft,atmospheric laser communication technology,optical micro-manipulation and laser processing.Based on the study of the Airy beam self-healing property,this paper focus on the recovery property of the focusd finite energy Airy beam,the lens correction method and the impact on it in different weather condition.The main findings are as follows:1.Based on the generalized Huygens-Fresnel diffraction integral formula,we deduce the intensity distribution expression of recovery focused finite energy Airy beam and do numerical simulation and analysis.2.As the distance along the propagation direction increases,the recovery focused finite energy Airy beam quickly decays,a phenomenon which limits the application of Airy beams.So we try to add a lens for calibrating the beam and deduce the intensity distribution expression of recovery focused finite energy Airy beam and do numerical simulation and analysis.3.Based on the diffracting theory,we study the recovery phenomenon of Airy beam under different weather conditions and then Airy beam intensity distribution is simulated,finally we make a discussion.The results showed that:within a certain distance,with the increase of propagation distance the recovery focused finite energy Airy beam decays quickly.Therefore Airy beam applications are limited.This paper shows the method of adding a lens to calibrate the beam.And from the new expression and its numerical simulation we can see that the applications of this beam can be expanded.And different weather conditions impact the recovery of the focus finite energy Airy beam in different ways,our study cover the impacts on recovery of the focus finite energy Airy beam in sunny day,light rain,moderate rain,haze,moderate snow,and we find that the impact on the beam increase gradually. |
