    Scientists demonstrate, for the time, a solid-state "MASER" capable of operating at room temperature, paving the way for its widespread adoption – as reported today in the journal Nature.

    MASER stands for Microwave Amplification by Stimulated Emission of Radiation. Devices based on this process (and known by the same acronym) were developed by scientists more than 50 years ago, before the first LASERs were invented. Instead of creating intense beams of light, as in the case of LASERs, MASERs deliver a concentrated beam of microwaves.

    Conventional MASER technology works by amplifying microwaves using hard inorganic crystals such as ruby, this process is known as "masing". However, the MASER has had little technological impact compared to the LASER because getting it to work has always required extreme conditions that are difficult to produce; either extremely low pressures, supplied by special vacuum chambers and pumps, or freezing conditions at temperatures close to absolute zero ( -273.15°C), supplied by special refrigerators. To make matters worse, the application of strong magnetic fields has often also been necessary, requiring large magnets.

    Now, the team from the National Physical Laboratory (NPL) and Imperial College London have demonstrated masing in a solid-state device working in air at room temperature with no applied magnetic field. Today's breakthrough means that the cost to manufacture and operate MASERs could be dramatically reduced, which could lead to them becoming as widely used as LASER technology.

    What would be the applications of this?

    Well when LASERS were first made they didn't know what they could do either and today they are still finding ways that they can be used. It is only a matter of time before we see this new technology being integrated into our society just as LASERS have done in the past 40 years or so since they became developed.
