The first practical continuous wave maser

Physicists at Imperial College London are currently working on a new project using one of Laser Quantum’s lasers – a practical continuous wave maser.

The maser (microwave amplification by stimulated emission of radiation) preceded the laser and has been confined to relative obscurity owing to its reliance on cryogenic refrigeration and high-vacuum systems following its inception in the 1950s. This may be set to change however, as a project at the London centre for nanotechnology is in the process of creating a continuous maser beam that can operate in room-temperature conditions. This project builds on research from 2012 by members of the same team, who created a device that worked at room temperature but only produced maser pulses. The latest device uses Laser Quantum’s finesse pure to provide a laser emission, which fills a diamond, sapphire and copper apparatus to create a continuous microwave emission.
