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 ...

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.
