How to break the FoV versus thickness rule in MCAO

Enlarging the searchable area for suitable reference stars in MCAO could allow to eliminate the need for lasers in ELTs. It has been previously claimed that this was not achievable because enlarging such a FoV would have diminished the thickness of the turbulence corrected by each DM. We show in this paper that there are ways to overcome this limitation.
