consensus on goals:

1

• consensus on goals
• science competitive edge of LUCIFER MOS
• we want a reliable system with low risks
• prompt realization of GLAO
• upgrade path to on-axis diffraction limited
  performance
• needs to be
  identified
• upgrade path to wide-field, modest Strehl,
  diffraction limited operations
• needs to be identified

• consensus on technology
• the lowest risk/affordable choice for GLAO in
  terms of laser technology
• at present is a pulsed
  Rayleigh system
• projection system should be independent of laser
  technology, be a single
• projector for each of the pupils
  and use simple reflective/lens optics,
• allowing both on-axis and off-axis
  projection schemes
• wave front sensors should not require immediate
  re-design of AGW units this may require that
  the wfs are outside the AGW units
• identify wfs detectors and suitability of pockel
  cells

• unknowns
• which is the best upgrade path ?
• benefit of LGSF to interferometry (given fringe
  tracking issues)
• how fast will a low cost, 3rd generation
  Na-laser be available commercially?
• impact of LGSF on operations commissioning
