Abstract

Laser beam pointing instability is one of the most actual problem at the artificial guide stars generation, because high angular stability (~1…2 arcsec) of laser beacons is required for atmosphreric compensation with adaptive optics. In our work we investigated the beam pointing stability of frequency-doubled Nd:YAG lasers generating at the wavelength of 532 nm. Such lasers may be used for guide stars generation by Rayleigh optical scattering by air molecules in the stratosphere [1].
