Frequently Asked Questions

Common questions about CPT Atomic Clocks

What is Coherent Population Trapping (CPT) technology?

CPT is an all-optical technique that interrogates the atomic resonance without a bulky microwave cavity, enabling atomic clocks with a far more compact structure and lower power consumption than traditional designs while retaining high frequency stability.

What applications are CPT atomic clocks suited for?

They are used for satellite navigation, underwater navigation, digital communication, and network synchronization, where precise timing must fit within tight size and power budgets.

Why choose a CPT clock over a larger frequency standard?

CPT clocks trade a modest amount of ultimate stability for major reductions in size, weight, and power, making them ideal for portable, airborne, and embedded platforms that cannot accommodate a rack-mounted standard.
