Scientists from UNSW have designed an innovative maser device based on purple diamonds. It will have the potential to boost weak microwave signals originating from distant celestial objects or ...
The team of quantum experts have developed a device known as a maser which uses a specially created purple diamond to amplify weak microwave signals, such as those which can come from deep space.
It seems like a science fiction MacGuffin: it uses a purple diamond in a quartz tube exposed to an intense magnetic field. The system creates a maser, the microwave equivalent of a laser.
