We report on two ultrastable lasers each stabilized to independent silicon Fabry-Perot cavities operated at 124 K. The fractional frequency instability of each laser is completely determined by the fundamental thermal Brownian noise of the mirror coa

Conference on Lasers and Electro-Optics.
Thermal noise is now limiting the most stable lasers that are employed in optical clocks and for precision measurements to a few times 10–17. Laser systems and ways towards further improvements will be presented.

Conference on Lasers and Electro-Optics.
We report on two ultrastable lasers stabilized to single-crystal silicon Fabry-Perot cavities at 124 K. The lasers show unprecedented thermal noise-limited frequency instabilities of 4×10−17 and linewidths below 10 mHz.

2016 Conference on Precision Electromagnetic Measurements (CPEM 2016).
The tremendous progress with optical atomic clocks asks for super-stable lasers to interrogate the best clock transitions with only a few mHz line width. Previously, we developed a cryogenic silicon Fabry-Perot resonator that demonstrated short-term

We have set up an improved vertically mounted silicon cavity operating at the zero-crossing temperature of the coefficient of thermal expansion (CTE) near 123 K with estimated thermal noise limited instability of 4 x 10-17 in the modified Allan devia

Diagnosis is the process of determining the correct problem from a collection of problems given a set of symptoms that indicate a problem exists. Common experiences with this process include visits to the physician in order to determine our illness (
