AtomiC Clock

Atomic clocks are one of the most precise systems for time measurement today, which utilizes the natural vibrations of atoms. The frequency of an atomic transition is extremely stable and can be used to measure time accurately by counting the number of vibrations that occur in a certain period of time.

Atomic clocks are already essential in telecommunication applications, where they are used to synchronize data transmission between devices. In navigation, atomic clocks are used in GPS satellites to accurately measure the time it takes for a signal to travel from the satellite to a GPS receiver on the ground to calculate the precise location.

Our single frequency lasers offer narrow linewidth and high output power, making them particularly suitable for atomic clocks. For example, our DFB lasers or our miniECLs can be used to excite Rubidium atoms at 780 nm or cesium based atomic clocks at 852 nm to their resonant state. Due the hermetically sealed package and the integrated thermal management, these lasers offer high stability and robustness, making them ideal for applications with harsh environments beyond the laboratory.
