Abstract
Second generation Adaptive Optical (AO) systems are being built or planned at many astronomical sites, which use Laser Guide Stars (LGS) as reference object in the wavefront sensor for the determination of wavefront aberrations. This is going to increase dramatically the sky coverage and the science throughput of AO systems used at astrophysical sites.
