In collaboration with member states institutes, the use of the synergies with ESO is producing first important results in the R&D for Laser Guide Star adaptive optics, to be used for the large and extremely large telescope projects.

In this talk we will report on the preliminary results of the current campaign on LGS return flux with laser guide stars at Observatorio de el Teide and the foreseen tests of the EELT LGS-AO scheme, to be done at the WHT starting in summer 2016. An outlook will be given on the proposal for further feasibility tests at WHT in 2018-19, to experiment novel LGS-AO schemes using uplink beam correction and pyramid wavefront sensing. The demonstration is for a LGS-AO scheme giving high Strehl on the EELT and adaptive optics in the visible on 8m class telescopes.
