In this thesis, a simple low-cost, characterized, statistically repeatable optical phase turbulence generator is described for application in multi-conjugate adaptive optics, simulating several layers of atmospheric turbulence. Amongst the different turbulence generator options such as phase plates, the only one matching the specifications is hot air turbulence. We present the results and the characteristics of the turbulence generated on the laboratory. It was decided to use turbulence layers conjugate to heights in the real atmosphere of 5 km and 15 km. Given the necessary folding of the beam, it was desirable to place the two turbulence layers so that a single turbulence generator box could be used by allowing two beam passes through the optical path. The experiment allows for having two well characterized turbulence with 1 < d/r0 < 20 for both the layers.
