The influence of high-frequency phase distortion on the phase correction effect in atmospheric turbulence

Intensity Distribution of Partially Coherent Array Finite Airy Beams Propagating in Atmospheric Turbulence

“…While C n 2 � 10 −11 m −2/3 , the transmission distance is z � 500 where the PCAFABs gradually degrade into the PCAGBs, as can be seen in Figure 4(f ). e singular properties of the PCAFABs cease to exist provided that its side lobes disappear entirely; therefore, while C n 2 � 10 −8 m −2/ International Journal of Optics x (ω 0 ) x (ω 0 ) x (ω 0 ) x (ω 0 ) International Journal of Optics 3 in Figure 4(j), the PCAFABs will never separate from each other in the rest of the atmospheric turbulence, and the spot size of these array beams increases in proportion to the Gaussian function with the increasing transmission distance until the power eventually burns out. We end up with this section by discussing the PCAFABs through atmospheric turbulence which contains different numbers of the single Airy beam so that the conclusions obtained are universal.…”

“…However, the diffraction and non-self-heal effects of Gaussian beam are very obvious in the transmission process when it meets obstacles or blocks [2]. Moreover, it is difficult to overcome the defects such as low energy utilization rate, large spot divergence angle, slow transmission rate, and high bit error rate for Gaussian beam even with the adoption of partial coherence technology [3]. erefore, it is becoming the research hot spot for science and engineering experts to find a kind of novel laser light source itself owning the ability to resist atmospheric turbulence in recent decades.…”

And it has potential applications in many fields such as optical micro-particles manipulation, generation of optical bullets, creating curved electron beams, formation of Airy beam lasers and so on.…”

Improving the performance of a laser-driven flyer with a diffractive optical element of high wavefront distortion tolerance

“…Research has reported that the low-frequency wavefront distortion will cause the irregular malformation of the focal spot of a laser beam [25]. In laser systems, lowfrequency wavefront distortion is caused by the surface distortion of the reflecting mirror, the transmission through optical elements, thermal effects, air turbulence, spherical aberration, and eccentric coma, etc [25][26][27][28]. The wavefront distortion is differently distributed under different experimental conditions and has different effects on focal spots, which is not expected.…”
