New POP Atomic Clock Design Achieves State-of-the-Art Frequency Stability
Chinese researchers have developed a pulsed optically pumped (POP) atomic clock with frequency stability of 4.7 × 10-15 at 104 seconds based on a new design. The achievement is noteworthy because atomic clocks — often considered the most stable frequency standard for timekeeping — are crucial components in global navigation systems and international communication services, ...
