When the laser was developed, Townes and Schawlow and their colleagues at Bell Labs pushed the use of the term optical maser, but this was largely abandoned in favor of laser, coined by their rival Gordon Gould.

However, this was ultimately changed to laser for "Light Amplification by Stimulated Emission of Radiation." Gordon Gould is credited with creating this acronym in 1957.

In 2012, a research team from the National Physical Laboratory and Imperial College London developed a way to make a solid-state maser operate at room temperatures by using pentacene-doped p-Terphenyl as the amplifier medium.

Independently, Charles H. Townes, James P. Gordon, and H. J. Zeiger built the first ammonia maser at Columbia University in 1953.
His principal teachers include Denis Wick, Robert Deahl, Al Lube, Carsten Svanberg, Phil Wilson, Michel Becquet, Allen Barnhill, John Marcellus, Leon Brown, and Dave Maser.
OH (1720 MHz) maser emission, which is a robust tracer of interaction between SNRs and dense molecular clouds, has been detected in this region.
Albert Einstein created the foundations for the laser and maser in 1917, via a paper in which he re-derived Max Planck’s law of radiation using a formalism based on probability coefficients (Einstein coefficients) for the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation.
Basov's contributions to the development of the laser and maser, which won him the Nobel Prize in 1964, led to new missile defense initiatives seeking to employ them.
In 1369 Philip de Mezières (also known as Filippo Maser), the Chancellor of the Kingdom of Jerusalem and the Kingdom of Cyprus, gave to the school a piece of the true cross which it still owns to this day.
