End Resonances for Atomic Clocks

Abstract

WE DISCUSS ADVANTAGES OF THE "END" RESONANCES FOR MINIATURIZED, CHIP-SCALE ATOMIC CLOCKS BASED ON ALKALI-VAPOR CELLS FILLED WITH HIGH-PRESSURE BUFFER GASES. Compared to the commonly used 0-0 resonance clock design, these advantages include a high signal-to-noise ratio, a narrower linewidth at high vapor densities, and a significantly reduced sensitivity to the frequency stability of the pump laser at high buffer-gas pressure. We report our measurements of the (133) Cs resonance linewidth for both 0-0 and end transitions, and give the estimates of the (133) Cs resonance-damping rates due to N(sub 2) buffer gas. Finally, we demonstrate a 1 kHz end resonance linewidth in a MEMS-fabricated microcell containing cesium and 1 atm N(sub 2).
