A Powerful new Laser Will Enhance Adaptive Optics
In some applications, bigger lasers mean better lasers. That is the case in astronomy, where lasers are used for everything from telescope calibration to satellite communication. The European Southern Observatory ([ESO](https://en.wikipedia.org/wiki/European_Southern_Observatory)) and some of its commercial partners have developed a laser 3 times more powerful than the existing industry standard. With that increased power level, the new system has the potential to dramatically improve the way telescopes deal with one of the most fundamental problems in ground-based astronomy - atmospheric turbulence.
