New Maser in a ‘Shoebox’ Promises Portable Precision

The new 'shoebox' maser in operation

Researchers in Imperial College London’s Department of Materials have developed a new portable maser that can fit the size of a shoebox.

Imperial College London pioneered the discovery of room-temperature solid-state masers in 2012, highlighting their ability to amplify extremely faint electrical signals and demonstrate high-frequency stability. This was a significant discovery because microwave signals can pass through the Earth’s atmosphere more easily than other wavelengths of light. Additionally, microwaves have the capability to penetrate through the human body, a feat not achievable by lasers.

Masers have extensive applications in telecommunications systems—everything from mobile phone networks to satellite navigation systems...
