Solar-pumped laser : ウィキペディア英語版 | Solar-pumped laser A solar-pumped laser is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium. This type of laser is unique from other types in that it does not require any artificial energy source. ==Lasing media==
The two most studied lasing media for solar-pumped lasers have been iodine,〔De Young et al. Preliminary Design and Cost of a 1-Megawatt Solar-Pumped Iodide Laser Space-to-Space Transmission Station, NASA Technical Memorandum, 1987 ((Original version ), (WebCite archive )), Retrieved 2011-06-23〕 with a laser wavelength of 1.31 micrometers, and NdCrYAG, which lases at 1.06 micrometers wavelength. Solar-pumped semiconductor lasers have also been proposed by Landis〔G.A. Landis, "New Approaches for a Solar-Pumped GaAs Laser," ''Optics Communications, 92'', pp 261-265 (1992). ((Abstract ))〕 and others.〔I.M. Tsidulko, "Semiconductor Laser Pumped by Solar Radiation," ''Soviet Journal of Quantum Electronics 22'' (5), pp. 463-466 (1992).〕
