<p><b>New page</b></p><div>A '''laser''' (the term originated as an acronym of 'light amplification by stimulated emission of radiation') is an optical device that can convert supplied energy into a beam of almost perfectly 'coherent' light (light whose [[photon]]s are of exactly identical [[wavelength]], perfectly in [[phase]], and travelling precisely in parallel, directionally). Such light has many uses.<br />
