Scientists from ITMO University’s Research Institute of Laser Physics have developed a high-power laser with short pulse duration for use in a lunar laser locator. The locator will make it possible to measure the distance between the Moon and Earth with a margin of error of just a few millimeters. This would make it possible to correct calculations of celestial coordinates of the Moon in order to improve the accuracy of satellite navigation systems. An article on the new laser was published in Optics Letters.
