MASER -Microwave Amplification by Stimulated Emission of Radiation.
LASER - Light Amplification by Stimulated Emission of Radiation.
With a LASER, we get uniform, coherent, monochromatic electromagnetic radiation of wave length in the visible and near visible range (1mm-10nm).
MASERs use microwaves instead and the wavelength is longer (1mm to 1m).
Since the energy of a photon can be calculated by Energy= h (Planks constant) x f (frequency) the energy in a MASER is less than that in a LASER all other things being the same.

A maser is a principle of?
A maser is a device that amplifies and emits electromagnetic radiation in the microwave region of the spectrum. It works on the principle of stimulated emission of radiation, similar to a laser but operating at longer wavelengths. Masers are used in scientific research, communication systems, and atomic clocks.
Why did Charles Hard Townes win The Nobel Prize in Physics in 1964?
The Nobel Prize in Physics 1964 was divided, one half awarded to Charles Hard Townes for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle,the other half jointly to Nicolay Gennadiyevich Basov and Aleksandr Mikhailovich Prokhorov for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle.
What is difference between three and four level laser?
The main difference between three and four level lasers lies in the energy levels involved in the lasing transition. In a three-level laser, the lasing transition occurs between the ground state and an excited state, while in a four-level laser, an additional intermediate energy level is used to facilitate the lasing process. This intermediate level enables four-level lasers to operate more efficiently at higher power levels compared to three-level lasers.
What is the main difference between laser and ordinary white light?
The main difference is that laser light is coherent, meaning the light waves are aligned and moving in a single direction, while ordinary white light is non-coherent, with light waves traveling in random directions. Laser light is also monochromatic, meaning it consists of a single color, while white light contains a mixture of different colors.
What is the difference between a laser pointer and an infrared laser pointer?
An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.
What is maser and laser?
maser : any of several devices that amplify or generate electromagnetic waves, especially microwaves.
How did Charles hard townes make a difference?
Charles Hard Towns made a difference in the world for his invention of the Laser and Maser. Without these life would be very difficult.
What is meant by masers?
A 'maser' is a 'laser' that amplifies and emits Microwave radiation instead of Light.
What is the difference between a river and a laser?
A laser is man-made, a river is natural.
What the difference between the laser unit of Noritsu QSS32 and QSS34?
There is no difference.
What is the difference between a laser printer and and a ink printer?
An ink jet printer simply prints. A color laser copier COPIES. This is the significant difference between the two.
Scientific discoveries that led to technological advances?
The invention of the Maser, followed soon after by the Laser allowed a huge spread of technologies. From surveying, through to the check-out counter, the laser is ubiquitous today.From a similar era, the computer, and its operational languages affect most parts of today's activities.Both the Maser and Laser are themselves technologies, but they followed on theoretical speculation and research.
What is difference between interposing voltage transformer and potential transformer?
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
What is the difference between personal and shared laser printer?
nothing
What is the difference between a ink jet printer and a color laser copier?
An ink jet printer simply prints. A color laser copier COPIES. This is the significant difference between the two.
What is a Five letter word ending in r?
Razor, Maser, Laser, Lover, Loner, Liver, Lager, Loser, Lader.
When were lasers created?
The idea of using visible light came around in the late '50's with the first patent attempt in 1958. The first working laser was made in 1960. It was based on an earlier invention called the MASER that used microwaves. The first thought about using infrared but then settled on visible light.Because it used visible light, the first patent used the term "optical MASER" instead of "LASER". The term LASER came from a paper in 1959 that spoke of the concept.LASER stands for: Light Amplification by Stimulated Emission of Radiation. (for MASER, replace "light" with "microwave")
