excimer laser

A gas laser in which a very short electrical pulse excites a mixture containing a halogen such as fluorine and a rare gas such as argon or krypton. It produces a brief, intense pulse of ultraviolet light. The output of an excimer laser is used for writing patterns on semiconductor chips, because the short wavelength can write very fine lines. In fiber optics, it is used to write fiber Bragg gratings.

excimer laser [′ek·sə·mər ‚lā·zər]

(optics)

A laser containing a noble gas, such as helium or neon, which is based on a transition between an excited state in which a metastable bond exists between two gas atoms and a rapidly dissociating ground state.
