Abstract
Concerning the problem of transmitting a laser beam from one telescope to another telescope through a turbulent medium, it is established that using an adaptive optical system on both telescopes to precompensate an outgoing laser beam based on the aberrations measured on the received laser beam leads to an iteration that maximizes the transmission (neglecting attenuation losses) of laser power between the telescopes. Simulation results are presented demonstrating the effectiveness of this technique when the telescopes are equipped with either phase-only or full-wave compensation systems. Simulation results are shown that indicate that for a uniform distribution of the strength of turbulence, 95% transmission of laser power is attained when both telescopes can achieve full-wave compensation provided that the aperture diameter <i>D</i> of the two telescopes is greater than twice the Fresnel length √λ<i>L</i>, where λ is the wavelength of propagation and <i>L</i> is the distance between the two telescopes.

- A convex set C is one in which, given any two points within said convex set, every point on the line connecting the two points is also contained in the set, i.e., ∀x_{1}, x_{2} ∈C, αx_{1} +(1−α)x_{2} ∈C, ∀α∈[0, 1]. As an example, the set describing the unit ball in a Hilbert space, C ={x∈H | |x|≤1}, is a convex set, whereas the set describing the boundary of the unit ball in a Hilbert space, C ={x∈H | |x|=1}, is nonconvex.
