Optical atomic clock review
WebJun 10, 2024 · These include the atomic clocks that provide U.S. official time or the signals from GPS satellites, by comparing their output to reference combs with frequencies 1,000 or more times higher. And it makes possible optical clocks with “tick” rates about 100,000 times faster than microwave models. Key Papers WebIn this review recent advances in attosecond science are reported and important applications are discussed. After a brief presentation of various techniques that can be employed for the generation and diagnosis of sub-femtosecond pulses, various applications are reported in atomic, molecular and condensed-matter physics.
