How do masers work compared to a laser?
Maser's emit photon's of lower frequency and longer wavelength compared to laser's.
This is how laser's and maser's work:
Electrons absorb an electric current or electromagnetic wave and become excited, which means they jump from a low energy state to a higher energy state. Then, when they drop back down into the lower energy state, the energy they must release to do so is released in the form of a photon. The photon's given off from electron's this way are all the same wavelength, and are focused in the same direction.
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 . The changes in frequency and wavelength come from the type of electromagnetic wave being absorbed, and/or the properties of the material emitting the photon's.
