Masers

Masers are devices that generate highly amplified microwave or radio frequency signals through a process called stimulated emission, similar to lasers but operating at microwave wavelengths. They use specific materials or gases that, when energized, produce coherent electromagnetic waves—meaning the waves are in sync and very stable. Masers are known for their exceptional precision and are used in advanced scientific applications like deep-space communication, atomic clocks, and radio telescopes to ensure extremely accurate frequency standards. Their ability to produce stable, narrow-band signals makes them crucial in fields that require precise measurement and timing.
