Laser vs. Maser

Lasernoun

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

Lasernoun

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

Lasernoun

A laser printer.

Lasernoun

A gum resin obtained from certain umbelliferous plants.

Lasernoun

Such a plant.

Laserverb

To cut with a laser

Laserverb

(sports) To throw with laser-like precision

Lasernoun

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).

Lasernoun

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

Laser

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word is an acronym for .

Masernoun

(physics) a device for the coherent amplification or generation of electromagnetic radiation (especially of microwave frequency) by the use of excitation energy in resonant atomic or molecular systems

Masernoun

(astronomy) Any celestial object that generates microwaves using the same method

Masernoun

Same as Mazer.

Masernoun

An electronic device producing coherent monochromatic microwave radiation; it produces less noise than other forms of microwave oscillator.

Masernoun

an acronym for microwave amplification by stimulated emission of radiation; an amplifier that works on the same principle as a laser and emits coherent microwave radiation

Maser

A maser (, an acronym for microwave amplification by stimulated emission of radiation) is a device that produces coherent electromagnetic waves through amplification by stimulated emission. The first maser was built by Charles H. Townes, James P. Gordon, and Herbert J. Zeiger at Columbia University in 1953.
