Laser Engineering and Applications
Atomic clocks are highly precise timekeeping devices that utilize the vibrations of atoms to measure time. By measuring the frequency of microwave radiation emitted or absorbed by atoms, typically cesium or rubidium, these clocks achieve unparalleled accuracy, making them essential for applications like GPS and telecommunications. Their precision is further enhanced through techniques like laser cooling, which reduces the thermal motion of atoms, allowing for more accurate frequency measurements.
