Light Shift Suppression in Coherent-Population-Trapping Atomic Clocks in the Field of Two Circularly Polarized Light Beams
D. V. Brazhnikov, S. M. Ignatovich, M. N. Skvortsov
The state-of-the-art miniature atomic clocks (MACs) are based on the phenomenon of coherent population trapping (CPT) in alkali-metal atomic vapors (Rb or Cs). Increasing frequency…
High-quality level-crossing resonances under counterpropagating circularly polarized light waves for applications in atomic magnetometry
D. V. Brazhnikov, V. I. Vishnyakov, S. M. Ignatovich +3
Level-crossing (LC) resonances in a buffer-gas-filled cesium vapor cell are studied under counterpropagating pump and probe light waves with opposite circular polarizations. The wa…
946-nm Nd:YAG digital-locked laser at in 1 s and transfer-locked to a cryogenic silicon cavity
A. Didier, S. Ignatovich, E. Benkler +2
We present a Nd:YAG ultra-stable laser system operating at 946 nm and demonstrate a fractional frequency instability of at 1 s by pre-stabilizing it to a 30 cm-…
Ultrahigh-Quality Magneto-Optical Resonances of Electromagnetically Induced Absorption in a Buffer-Gas-Filled Vapor Cell
Denis Brazhnikov, Stepan Ignatovich, Vladislav Vishnyakov +4
A new configuration for observation of magneto-optical subnatural-linewidth resonances of electromagnetically induced absorption (EIA) in alkali vapor has been verified experimenta…
Simple vibration insensitive cavity for laser stabilization at the 10^{-16} level
Jonas Keller, Stepan Ignatovich, Stephen A. Webster +1
We present the design and realization of two reference cavities for ultra-stable lasers addressing narrow transitions in mixed-species (In+ / Yb+) Coulomb crystals. With a simple s…
