    There are two main types of laser guide star system, known as sodium and Rayleigh beacon guide stars. Sodium beacons are created by using a laser tuned to 589.2 nanometers to energize atoms in the sodium layer of the mesosphere at an altitude of around 90 km (56 mi). The sodium atoms then re-emit the laser light, producing a glowing artificial star. The guide stars are actually emission from laser excited sodium atoms at high altitudes within the telescopic field of view. Guide star image fluctuations are used in real-time to correct for atmospheric blurring by controlling a deformable mirror in the telescope's optical path. Known as adaptive optics, the technique can produce images at the

    The new Four Laser Guide Star Facility, which ESO touted as the most powerful of its kind in the world, fires four 22-watt lasers into the upper atmosphere, where they hit sodium atoms and make by the laser as it propagates up to form an arti cial guide star and the global tip-tilt across the telescope aperture as it propagates back. It should be noted that the tip-tilt ob-served by the laser will be larger than that seen by the full aperture due to greater spatial averaging on larger scales.
