Propagation Properties of HermiteGaussian Beams in NonKolmogorov Turbulence
Based on the extended HuygensFresnel principle and nonKolmogorov spectrum, analytical expressions for the beam width, angular spread and M2factor of HermiteGaussian (HG) beams through nonKolmogorov turbulence are derived. The results show that at a sufficiently long propagation distance(such as z≥3 km), the beam width, angular spread and the M2factor of HG beams through nonKolmogorov turbulence all increase with the increasing outer scale L0(3.6<α<4)and decreasing inner scale l0, and increase with the increasing exponent parameter α until it reaches its maximum value at α=3.11, then decrease with increasing α. However, the beam width and M2factor of HG beams hardly vary with increasing outer scale L0 in the region 3<α<3.6.
