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. How do masers work compared to a laser? Solace M. May 29, Maser's emit photon's of lower frequency and longer wavelength compared to laser's. Explanation: 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.

When atoms have been induced into an excited energy state, they can amplify radiation at a frequency particular to the element or molecule used as the masing medium similar to what occurs in the lasing medium in a laser. S2CID Masers are also used as the timekeeping device in atomic clocks , and as extremely low-noise microwave amplifiers in radio telescopes and deep-space spacecraft communication ground stations. Gordon Gould is credited with creating this acronym in Apr 29, 1, Gordon , and H. Amplification was achieved by exciting a ruby comb with a Electronic components. Emerging technologies.

Since ancient times, people believed that rays of light carry grand and mysterious powers.

For this reason, Townes suggested replacing "microwave" with "molecular" as the first word in the acronym "maser". The principle and concept of stimulated emission has since been extended to more devices and frequencies. Maiman created the first working model in Categories : American inventions Laser types Microwave technology Optical devices Russian inventions 20th-century inventions. Physical Review. You must log in or register to reply here. When the coherent optical oscillator was first imagined in , it was originally called the "optical maser". Gordon Gould is credited with creating this acronym in In , a research team from Imperial College London and University College London demonstrated continuous-wave maser oscillation using synthetic diamonds containing nitrogen-vacancy defects. In the early years, it took days to chill and remove the impurities from the hydrogen lines. March The Astrophysical Journal. Wikimedia Commons.
