Optics Letters, 2016 We show theoretically that it is feasible to generate a spectrally broad Kerr frequency comb consisting of several spectral clusters phase matched due to interplay among second- and higher-order group velocity dispersion contributions. We validate the theoretical analysis experimentally by driving a magnesium fluoride resonator, characterized with 110 ...

Simple single-section diode frequency combs
APL Photonics, 2020 Frequency combs, broadband light sources whose spectra consist of coherent, discrete modes, have become essential in many fields. Miniaturizing frequency combs would be a significant advance in these fields, enabling the deployment of frequency-comb ...

Studying the effect of fluctuating environment on intra-atomic frequency comb based quantum memory
Scientific Reports, 2021 In this article, we study the effect of various environmental factors on intra-atomic frequency comb (I-AFC) based quantum memory. The effect of the environment is incorporated as random fluctuations and non-uniformity in the parameters such as comb ...

XUV FREQUENCY COMB SPECTROSCOPY
Laser Spectroscopy, 2010 We report the first demonstration of frequency comb metrology at extreme ultraviolet wavelengths (XUV), based on parametric amplification and high-harmonic generation of frequency comb pulses, which results in an 8-fold improved helium ionization potential.

Laser Spectroscopy and Frequency Combs
Journal of Physics: Conference Series, 2013 The spectrum of a frequency comb, commonly generated by a mode-locked femtosecond laser consists of several hundred thousand precisely evenly spaced spectral lines. Such laser frequency combs have revolutionized the art measuring the frequency of light, and they provide the long-missing clockwork for optical atomic clocks.
