Laser with stability
Ben Lewis, Zoey Z. Hu, Dahyeon Lee +8
We report a laser with record frequency stability, based on a 21 cm cryogenic silicon cavity. For best short-term stability, the cavity operates at 6 K to minimize Brownian thermal…
Laser stabilized to a room temperature cavity with AlGaAs coatings reaching fractional frequency instability
Chun Yu Ma, Jialiang Yu, Steffen Sauer +6
We present a laser system referenced to a room-temperature ultrastable cavity employing crystalline AlGaAs coatings. We demonstrate a fractional frequency instability of $4.2 \time…
Photo-birefringent effects in crystalline AlGaAs mirror coatings
Chun Yu Ma, Jialiang Yu, Thomas Legero +5
High-reflective crystalline coatings show reduced Brownian noise compared to conventional dielectric coatings. However, several ultra stable laser syste…
Frequency stability of in a Si cavity with AlGaAs crystalline mirrors
Dahyeon Lee, Zoey Z. Hu, Ben Lewis +8
Developments in ultrastable lasers have fueled remarkable advances in optical frequency metrology and quantum science. A key ingredient in further improving laser frequency stabili…
Ultrastable lasers: investigations of crystalline mirrors and closed cycle cooling at 124 K
C. Y. Ma, J. Yu, T. Legero +8
We have investigated crystalline AlGaAs/GaAs optical coatings with three ultra-stable cavities operating at 4 K, 16 K, 124 K and 297 K. The response of the resonance frequencies of…
Interrogation laser for a strontium lattice clock
T. Legero, Ch. Lisdat, J. S. R. Vellore Winfred +4
We report on the setup and characterization of a 698 nm master-slave diode laser system to probe the 1S0-3P0 clock transition of strontium atoms confined in a one-dimensional optic…
