A laser guide star facility is currently being planned for the LBT. The first step of the program aims at the implementation of a ground layer adaptive optics (GLAO) system tailored on the wide-field imager / multi-object spectrograph LUCIFER having a 4x4' FoV. The current design is based on multiple Rayleigh guide stars arranged in a 2-5 arcmin angular radius constellation. A future update path toward small-field diffraction limited performances is foreseen using a hybrid system of sodium and Rayleigh beacons promising lower power requirements for the sodium laser. In this paper we present the estimated performances for both the GLAO and the hybrid implementations and we introduce the wavefront sensors opto-mechanical design . Simulations of the GLAO system show an expected gain in FWHM and encircled energy of 1.5-3 (depending on atmospheric turbulence profiles) with a FWHM variation over LUCIFER FoV below 10% and point out the role of such a GLAO system as PSF stabilizer both over the FoV and with respect to seeing temporal variations. Results of simulations for the hybrid configurations will be presented.
