Before the laser: the maser

Показать описание
Lasers are everywhere, and provide intense beams of light for a range of things, from CD players to precision-welding, to eye surgery. But before the laser, came the maser. Instead of amplifying visible light that lasers do, masers amplify microwaves. Microwaves are the section of the electromagnetic spectrum that support our mobile phone and satellite networks, Bluetooth or WiFi, or 3G or 4G.
Amazing masers: selected for the Royal Society Summer Science Exhibition 2017
