| laser |
a device that amplifies electrical impulses at mixed frequencies in or near the range of visible light by stimulating the atoms in a medium such as a gas or crystal, producing an intense, concentrated beam of light at one or more virtually distinct frequencies (acronym for "light amplified by stimulated emission of radiation"). |
| lattice |
in physics, the regularly spaced arrangement of points or matter throughout a space, as in a crystal. [1/3 definitions] |
