Long-Term Frequency Instability of CPT Clocks With Microfabricated Vapor Cells

April 1, 2006

Author(s)

Vladislav Gerginov, Svenja A. Knappe, P Schwindt, V Shah, Leo W. Hollberg, John E. Kitching

We present an evaluation of the long-term frequency instability and environmental sensitivity of a chip-scale atomic clock based on coherent population trapping, particularly as affected by the light source subassembly. We find that the clock frequency is

Atom-based stabilization for laser-pumped atomic clocks

March 27, 2006

Author(s)

Vladislav Gerginov, V Shah, Svenja A. Knappe, Leo W. Hollberg, John E. Kitching

Progress towards simplification and improvement of the long-term stability of chip-scale atomic clocks is presented. The conventional technique of laser optical frequency and cell temperature control is compared with a novel technique which avoids the use

High-Contrast CPT Resonances

February 7, 2006

Author(s)

John E. Kitching

The performance of an atomic clock or magnetometer based on CPT is determined by the resonance width and the signal-to-noise ratio. In particular, a large signal amplitude results in a high stability for a clock or a high sensitivity for a magnetometer

Long-term Frequency Stability of Chip-Scale Atomic Clocks

January 26, 2006

Author(s)

Vladislav Gerginov, Svenja A. Knappe, V Shah, P Schwindt, Leo W. Hollberg, John E. Kitching

We present an evaluation of the long-term frequency instability and environmental sensitivity of a chip-scale atomic clock based on coherent population trapping (CPT), particularly as affected by the light source subassembly. The long-term frequency

Chip-Scale Atomic Devices at NIST

January 25, 2006

Author(s)

John E. Kitching

The NIST program on chip-scale atomic devices (CSAD) seeks to design, build and characterize miniature atomic instruments and sensors based on fabrication techniques traditionally used in the field of microelectronics and micro-electric-mechanical systems
