Many scientific, military, medical and commercial laser applications have been developed since the invention of the laser in 1958. The coherency, high monochromaticity, and ability to reach extremely high powers are all properties which allow for these specialized applications. ==Scientific== In science, lasers are used in many ways, including: * A wide variety of interferometric techniques'' * Raman spectroscopy * Laser induced breakdown spectroscopy * Atmospheric remote sensing'' * Investigating nonlinear optics phenomena * Holographic techniques employing lasers also contribute to a number of measurement techniques. * Laser based lidar (LIght raDAR) technology has application in geology, seismology, remote sensing and atmospheric physics. * Lasers have been used aboard spacecraft such as in the Cassini-Huygens mission. * In astronomy, lasers have been used to create artificial ''laser guide stars'', used as reference objects for adaptive optics telescopes. Lasers may also be indirectly used in spectroscopy as a micro-sampling system, a technique termed Laser ablation (LA), which is typically applied to ICP-MS apparatus resulting in the powerful LA-ICP-MS. The principles of laser spectroscopy are discussed by Demtröder〔W. Demtröder, Laser Spectroscopy, 3rd Ed. (Springer, 2009)〕 and the use of tunable lasers in spectroscopy are described in Tunable Laser Applications.〔F. J. Duarte (Ed.), Tunable Laser Applications, 2nd Ed.
