Implementation of a single femtosecond optical frequency comb for rovibrational cooling

, 2010
We show that a single femtosecond optical frequency comb may be used to induce two-photon transitions between molecular vibrational levels to form ultracold molecules, e.g., KRb.

Optical frequency combs and optical frequency measurements

, 2014
Self-referenced optical frequency combs are nowadays the instrument of choice in time and frequency metrology when dealing with high accuracy and stability measurements of optical frequencies. Beyond this purely measurement activity, they also have new high performance applications, such as low phase noise microwave generation and transfer of spectral ...

Determination of the zero-position for an optical angle sensor

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
This paper proposes a new optical angle sensor, in which a mode-locked femtosecond laser referred to as the optical frequency comb is employed as the light source for the sensor.

Impact of Decoherence on Internal State Cooling using Optical Frequency Combs

, 2012
We discuss femtosecond Raman type techniques to control molecular vibrations, which can be implemented for internal state cooling from Feshbach states with the use of optical frequency combs with and without modulation.

Coal‐Based Anthraquinone Synthesized by Cascade Catalytic Hydrogenation and Oxidation

Carbon and Hydrogen, EarlyView.
A cascade catalytic process has been proposed for the conversion of AN into the valuable AQ, utilizing a Pt/6MoOx/Al2O3 catalyst for hydrogenation to DHA and a RuOx‐Ce0.7Zr0.3O2 catalyst for oxidation, thus presenting an efficient route from coal to high‐value chemicals.

Low-noise transfer of the spectral purity of an optical comb line using a feedforward scheme

Journal of the European Optical Society-Rapid Publications, 2020
We present a detailed frequency noise analysis of a feedforward scheme used to faithfully transfer the spectral properties of an individual line of an optical frequency comb spectrum to a single-mode laser and in this way indirectly amplify it, which is ...
