A new study shows that when combined with lasers, atomic clocks can help us catch the most mysterious matter in the universe.

In an optical atomic clock, atoms are irradiated by laser light. If the laser has the correct frequency, the atoms change their quantum-mechanical state. For this purpose, the atoms have to be ...

R esearchers have developed a new approach in optical atomic clocks that brings forth a major goal in science: the redefinition of a second. The fundamental unit of time could soon be based on ...

Optical atomic clocks represent a significant advancement in timekeeping technology, utilizing the precise oscillations of atoms to measure time with unprecedented accuracy. These clocks rely on ...

Adtran today launched its Enhanced Short-Term Unit (ESTU) precision timing module, a new addition to its OSA 3300 ...

Adtran today announced that the Brazilian National Observatory (Observatório Nacional) has integrated its OSA 3300 Super High ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

“This advanced ESTU module enhances our industry-first high-performance optical cesium atomic clocks, delivering substantial benefits, including reduced Allan Deviation. These improvements are ...

has integrated its OSA 3300 Super High-Performance optical cesium atomic clock into its timekeeping infrastructure. The deployment marks the first use of an optical pumping cesium clock at the ...
