Program (lrrp) in fy02 in response to 1) concerns about the risk of space-based lidar missions, 2) november 2000 report of an independent laser review panel, and 3) the june.
Lasers have also been used in instruments that map the surfaces of planets, moons, and asteroids scientists have even measured the distance between the moon and earth using lasers by measuring the amount of time it takes for a laser beam to travel to the moon and back, astronomers can tell exactly how far away it is. Laser: laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. 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. Optics & laser technology aims to provide a vehicle for the publication of a broad range of high quality research and review papers in those fields of scientific and engineering research appertaining to the development and application of the technology of optics and lasers.
