A maser 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.
What does maser mean?
The first maser was built by the American physicist Charles H. Townes and his colleagues in 1953. The name is an acronym derived from “microwave (or molecular) amplification by stimulated emission of radiation.”
What does maser mean and how is it produced?
A maser (/ˈmeɪzər/, an acronym for microwave amplification by stimulated emission of radiation) is a device that produces coherent electromagnetic waves through amplification by stimulated emission.
What is the difference between a laser and a maser?
The difference between a laser and a maser is that the photon from a laser comes in the form of visible light , while a photon from a maser comes in the form of a microwave . ... M.A.S.E.R. Stands for Microwave Amplification by Stimulated Emission of Radiation.
Which is more powerful laser or maser?
The electrons in masers are hit by some form of electromagnetic waves, which excite the electrons to a higher energy level, and when the electrons move down to a lower energy level, they emit a photon with a longer wavelength and lower frequency (less energy) than a laser.

What are three types of lasers?
- Solid-state laser.
- Gas laser.
- Liquid laser.
- Semiconductor laser.
What are uses of laser?

- Laser Material Processing.
Which of the following is an advantage of laser?
The advantages of laser cutting are flexibility, precision, repeatability, speed, cost-effectiveness, great quality, contactless cutting, versatility and automation possibilities.
What is ruby maser?
Ruby masers are very low-noise pre-amplifiers used in the microwave receiving systems of the Deep Space Instrumentation Facility (DSIF) and the Deep Space Network (DSN) since 1960.
What does Mazer mean in English?
: a large drinking bowl originally of a hard wood.
What are hydrogen masers used for?
A hydrogen maser, also known as hydrogen frequency standard, is a specific type of maser that uses the intrinsic properties of the hydrogen atom to serve as a precision frequency reference. Both the proton and electron of a hydrogen atom have spins.
What nationality is maser?
German and English: from Middle High Germanmaser, Middle English maser 'maple-wood bowl' (Old French masere, of Germanic origin), hence a metonymic occupational name for a wood-turner producing such ware. ...
How much does a hydrogen maser cost?
Each hydrogen maser costs about $300,000 and has a limited lifetime; but the stability of a time scale is a function of the square root of the number of clocks, meaning that a large number of masers is required to modestly improve performance.
What is the basic principle of laser?
A laser emits a beam of electromagnetic radiation that is always monochromatic, collimated and coherent in nature. Lasers consist of three main components: a lasing medium (solid, liquid or gas), a stimulating energy source (pump) and an optical resonator; and have a wide variety of uses in clinical medicine.
What type of laser is the most powerful?
The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts – two petawatts – for an incredibly short duration, approximately a trillionth of a second or ...
How does a laser work and its application?
Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. Laser is an acronym for “light amplification by the stimulated emission of radiation.” ...
What are the characteristics of laser?
- High intensity.
What is the use of laser in communication?
Lasers in Communications
Laser light is used in optical fiber communications to send information over large distances with low loss. Laser light is used in underwater communication networks. Lasers are used in space communication, radars and satellites.
What are the three main properties of laser?
Lasers have three properties: coherency, collimation and monochromatic properties. These three properties of lasers produce a small focus point of intense power. This focused power is what makes laser light useful for cutting and welding.
Which is the first laser in the world?
Theodore Maiman made the first laser operate on 16 May 1960 at the Hughes Research Laboratory in California, by shining a high-power flash lamp on a ruby rod with silver-coated surfaces. He promptly submitted a short report of the work to the journal Physical Review Letters, but the editors turned it down.
Which is correct about laser?
Explanation: The lasers are highly directional having almost no divergence. The output beam of laser has a well-defined wave front due to which it can be focused on a point. Lasers are highly intense compared to ordinary light. They are monochromatic and coherent.
