Optical frequency combs (OFCs) provide a convenient reference for the frequency stabilization of continuous-wave lasers. We demonstrate a frequency control method relying on tracking over a wide range and stabilizing the beat note between the laser and the OFC. The approach combines fast frequency ramps on a millisecond timescale in the entire mode-hop free tuning range of the laser and precise stabilization to single frequencies. We apply it to a commercially available optical parametric…

Accurate laser frequency locking to optical frequency combs under low-signal-to-noise-ratio conditions.

We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb under conditions where the signal-to-noise ratio is low, too low to accommodate

Mid-infrared electro-optic dual-comb spectroscopy with feedforward frequency stepping.

In this Letter, we utilize an acoustic-optic frequency shifter in a feedforward manner for automatic interpolation of dual-comb spectroscopy, where frequency tuning can be achieved at 5.45 THz/s with



Phase-locked widely tunable optical single-frequency generator based on a femtosecond comb.

Tunable terahertz frequencies that are phase locked to a microwave reference, such as a Cs atomic clock, and high-precision interferometry could benefit greatly from the stability and accuracy of this widely tunable source.

Method for independent and continuous tuning of N lasers phase-locked to the same frequency comb.

We present a method of phase locking any number of continuous-wave lasers to an optical frequency comb (OFC) that enables independent frequency positioning and control of each laser while still

Frequency-comb-referenced singly-resonant OPO for sub-Doppler spectroscopy.

To test the spectroscopic performance of the OPO, saturation spectroscopy of several transitions belonging to the ν1 rovibrational band of CH₃I was carried out, resolving their electronic quadrupole hyperfine structure, estimating a linewidth better than 200 kHz FWHM for the idler, and determining the absolute frequency of the hyperfine components with a 50-kHz-uncertainty.

Continuously tunable, precise, single frequency optical signal generator.

This work demonstrates experimentally two fundamental aspects of optical frequency synthesis, namely, precise setting of the laser frequency at an arbitrary pre-determined value, and continuous tuning of the Laser frequency with the digital precision known in radio frequency synthesis.

Frequency-comb-referenced tunable diode laser spectroscopy and laser stabilization applied to laser cooling.

The megahertz-level stability and absolute frequency required are realized by stabilizing a distributed-feedback semiconductor laser to a frequency comb, and the employed technique could find wider use in precision spectroscopy.

Sweep optical frequency synthesizer with a distributed-Bragg-reflector laser injection locked by a single component of an optical frequency comb.

Doppler-free spectroscopy using a continuous-wave optical frequency synthesizer.

A continuous-wave (cw) optical frequency synthesizer is demonstrated by using a monolithic-type cw optical parametric oscillator ( cw-OPO) and an optical frequency comb and it is possible to tune the frequency continuously over 10 GHz.
