A laser frequency comb is a broad spectrum composed of equidistant narrow lines. Initially
invented for frequency metrology, such combs enable new approaches to spectroscopy over …

Over the past dozen years, optical frequency combs have evolved into valuable tools for
broadband molecular spectroscopy. They have already enabled remarkable advances for …

Laser frequency combs are coherent light sources that emit a broad spectrum of discrete,
evenly spaced narrow lines whose absolute frequency can be measured to within the …

Optical frequency combs offer enormous potential in the detection and control of atoms and
molecules by combining their vast spectral coverage with the extremely high spectral …

Besides serving as a frequency counter or clockwork, an optical frequency comb can be
used directly for spectroscopy, thus the name Direct Frequency Comb Spectroscopy (DFCS) …

We demonstrate a dual-comb spectrometer using stabilized frequency combs spanning 177
to 220? THz (1360 to 1690? nm) in the near infrared. Comb-tooth-resolved measurements of …

We describe a dual-comb spectrometer that can operate independently of laboratory-based
rf and optical frequency references but is nevertheless capable of ultra-high spectral …

The spectrum of a laser frequency comb consists of several hundred thousand equally
spaced lines over a broad spectral bandwidth. Such frequency combs have revolutionized …

We overcome the resolution limit of Fourier-transform spectrometry and measure
instrumental line-shape-free broadband molecular spectra with lines narrower than the …

Cavity-enhanced direct frequency comb spectroscopy combines broad spectral bandwidth,
high spectral resolution, precise frequency calibration, and ultrahigh detection sensitivity, all …
