“…This ability to rapidly cover thousands of cm −1 with high sensitivity and high resolution will be a powerful new tool for the study of ions and radicals for many applications. In addition, applications to other many other spectral regions are possible by using different comb sources combined with non-linear optics for covering the near-IR [65,66] or mid-IR [67,68,69,70,71]. These sources plus readout systems using different cameras or optical up-conversion [72] create the possibility of ion spectroscopy anywhere from the visible to the mid-IR.…”

Precision spectroscopy of trapped HfF + will be used in a search for the permanent electric dipole moment of the electron (eEDM). While this dipole moment has yet to be observed, various extensions to the standard model of particle physics (such as supersymmetry) predict values that are close to the current limit. We present extensive survey spectroscopy of 19 bands covering nearly 5000 cm −1 using both frequency-comb and single-frequency laser velocity-modulation spectroscopy. We obtain high-precision rovibrational constants for eight electronic states including those that will be necessary for state preparation and readout in an actual eEDM experiment.

“…Progress towards longer wavelengths has recently yielded new direct OFC sources, including the Tm:fiber laser operating at 2 µm [48] and the Cr 2+ :ZnSe laser operating at 2.4 µm [49]. Longer wavelengths can also be reached via nonlinear processes, by Raman shifting [50], difference-frequency generation [51][52][53], or with optical parametric oscillators [54][55][56][57]. The latter two provide spectral access to the important molecular fingerprint region located above 3 µm.…”

Cavity-enhanced optical frequency comb spectroscopy in the mid-infrared application to trace detection of hydrogen peroxide. Abstract We demonstrate the first cavity-enhanced optical frequency comb spectroscopy in the mid-infrared wavelength region and report the sensitive real-time trace detection of hydrogen peroxide in the presence of a large amount of water. The experimental apparatus is based on a midinfrared optical parametric oscillator synchronously pumped by a high-power Yb:fiber laser, a high-finesse broadband cavity, and a fast-scanning Fourier transform spectrometer with autobalancing detection. The comb spectrum with a bandwidth of 200 nm centered around 3.76 µm is simultaneously coupled to the cavity and both degrees of freedom of the comb, i.e. the repetition rate and carrier envelope offset frequency, are locked to the cavity to ensure stable transmission. The autobalancing detection scheme reduces the intensity noise by a factor of 300, and a sensitivity of 5.4 × 10 −9 cm −1 Hz −1/2 with a resolution of 800 MHz is achieved (corresponding to 6.9 × 10 −11 cm −1 Hz −1/2 per spectral element for 6000 resolved elements). This yields a noise equivalent detection limit for hydrogen peroxide of 8 parts-per-billion (ppb); in the presence of 2.8 % of water the detection limit is 130 ppb. Spectra of acetylene, methane, and nitrous oxide at atmospheric pressure are also presented, A. Foltynowicz ( ) · Applied physics. B, Lasers and optics (Print),

“…As a result, two new beams are generated: a signal and idler. OPOs pumped by 1.06 and 1.55 µm frequency combs allow to convert the radiation typically into the 3-4 µm range [48].…”

Abstract. For the last decade a very attractive field of laser physics, namely the optical frequency comb technique, has been intensively developed. Fiber lasers play particular role in that area. The motivation of their development is obtaining broadband comb systems with well-defined and stable mods (comb teeth). This paper presents a basic overview devoted to the fiber-based optical frequency combs.
