Everyone has heard of lasers, but hardly anyone outside of a physics lab or a science fiction novel has heard of a maser. Despite the fact that it was the precursor of the laser, the maser has been ...

A team of physicists has published a paper detailing how it developed the first ever maser to work at room temperature with the help of a homebaked crystal and a laser bought on eBay. Masers ...

While it has become a word, laser used to be an acronym: “light amplification by stimulated emission of radiation”. But there is an even older technology called a maser, which is the same acronym but ...

Scientists have used the same technology that brought us time crystals to create a room-temperature maser—a microwave laser—that overcomes many of masers’ past problems. Masers predate lasers. They’re ...
