Nikolay Basov, Alexander Prokhorov and Joseph Weber introduced the concept of the maser in 1952, and Charles H. Townes, James P. Gordon, and Herbert J. Zeiger built the first maser at Columbia University in 1953.

Jan 27, 2005 · Townes and his colleagues built the first maser in 1954. They sent a beam of excited ammonia molecules into a resonant cavity. Emission became self-sustaining as radiation from molecules in the cavity stimulated further radiation from the continuously renewed supply of excited molecules.

Aug 16, 2012 · Using spare chemicals, a laser bought on eBay and angst from a late-night argument, physicists have got the world's first room-temperature microwave laser working. The achievement comes nearly 60...

Maser, device that produces and amplifies electromagnetic radiation in the microwave range of the spectrum. The first maser was built by the American physicist Charles H. Townes. Its name is an acronym for “microwave amplification by stimulated emission of radiation.”

This work produced the first prototype of what later evolved into the laser (originally called "optical maser") and became one of the most important workhorses in 20th-century technology. [7] Gordon's later contribution to lasers included the analysis of …

Aug 22, 2022 · The first MASER was invented by three physicists named Charles Hard Townes, James P. Gordon and Herbert J. Zeiger in 1953. The MASER uses stimulated emission in a stream of energized ammonia molecules to amplify the microwaves.

The first maser device, which used ammonia gas, was built in December 1953. In 1958, Townes and a colleague outlined the principle of the optical maser, or laser. They speculated that a maser could deliver infrared or even visible light instead of microwaves.

Aug 15, 2012 · Physicists build first practical maser. Using spare chemicals, a laser bought on eBay and angst from a late-night argument, physicists have got the world's first room-temperature microwave laser...

Jan 2, 2024 · Charles H Townes first imagined the mechanics for MASERs (Microwave Amplification by Stimulated Emission of Radiation) in 1951. He then spent the next three years, along with fellow physicists, James P. Gordon and Herbert J. Zeiger, to …

Sep 17, 2014 · While the laser has some of its foundation built on its early relative, the maser (or microwave amplification stimulated by emission of radiation) actually has its own invention story. Read on to learn more about the maser and how it paved way for the “optical maser.”
