Query: Influence of atmospheric turbulence on states of light carrying orbital
  angular momentum   We have experimentally studied the degradation of mode purity for light beams
carrying orbital angular momentum (OAM) propagating through simulated
atmospheric turbulence. The turbulence is modeled as a randomly varying phase
aberration, which obeys statistics postulated by Kolmogorov turbulence theory.
We introduce this simulated turbulence through the use of a phase-only spatial
light modulator. Once the turbulence is introduced, the degradation in mode
quality results in cross-talk between OAM modes. We study this cross-talk in
OAM for eleven modes, showing that turbulence uniformly degrades the purity of
all the modes within this range, irrespective of mode number.
