Lazar vs. Laser

A diseased person; a leper.

Any of several devices that emit highly amplified and coherent radiation of one or more discrete wavelengths. One of the most common lasers makes use of atoms in a metastable energy state, which, as they decay to a lower energy level, stimulate others to decay, resulting in a cascade of emitted radiation.

(archaic) leper: a person suffering from Hansen's disease; a person suffering any contagious disease requiring similar isolation.

A beam of radiation emitted by a laser.

(archaic) leprous: afflicted by Hansen's disease; afflicted by any contagious disease requiring similar isolation.

(Sports)A ball or puck sent in a straight line at high speed

A person infected with a filthy or pestilential disease; a leper.

A device that produces a monochromatic, coherent beam of light.

A person afflicted with leprosy

A beam of light produced by such a device; a laser beam.

A laser printer.

A gum resin obtained from certain umbelliferous plants.

Such a plant.

To cut with a laser.

(sports) To throw or kick with laser-like precision.

A device which produces an intense, usually narrow, monochromatic beam of coherent light; called also optical maser. It has various forms, and is used in various applications in science and technology. The beam is produced by boosting the majority of the electrons in specific radiation-absorbing atoms in a medium into a higher energy level, from which they are stimulated by their own emitted radiation to drop back synchronously to their lower energy level, and emit light which is in phase (coherent).

An acronym for light amplification by stimulated emission of radiation; an optical device that produces an intense monochromatic beam of coherent light
