In order to ensure high and homogeneous image quality over the MICADO field of view and high sky coverage, the baseline is to operate wavefront sensing using six Sodium Laser Guide Stars. The Laser Guide Star Wavefront Sensor (LGS WFS) is the MAORY sub-system devoted to real-time measurement of the high order wavefront distortions. In this paper we describe the MAORY LGS WFS current design, including opto-mechanics, trade-offs and possible future improvements.STAMPAenThe MAORY laser guide star wavefront sensor: design statusConference paper10.1117/12.23144672-s2.0-85053553813000452819300062https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10703/2314467/The-MAORY-laser-guide-star-wavefront-sensor-design-status/10.1117/12.2314467.short2018SPIE10703E..1YSFIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
