Laser beam complex amplitude measurement by phase diversity

Autor: Védrenne, Nicolas, Mugnier, Laurent M., Michau, Vincent, Velluet, Marie-Thérèse, Bierent, Rudolph

The control of the optical quality of a laser beam requires a complex amplitude measurement able to deal with strong modulus variations and potentially highly perturbed wavefronts. The method proposed here consists in an extension of phase diversity

International audience; High capacity GEO-Feeder optical links are very promising but constitute a real challenge for the whole transmission chain. The modeling and mitigation of turbulence effects is a particularly critical issue that drives the oth
