Accuracy comparison of absolute optical frequency measurement between harmonic-generation synthesis and a frequency-division femtosecond comb
نویسندگان
چکیده
Using an iodine-stabilized He-Ne laser as a transfer oscillator, we compare absolute measurements of the optical frequency from a traditional frequency synthesis chain based on harmonic generation and from the frequency division technique of an ultrawide bandwidth femtosecond frequency comb. The agreement between these two measurements, both linked to the Cs standard, is 220+/-770 Hz, yielding a measurement accuracy of 1.6x10(-12). We report 473 612 353 604.8+/-1.2 kHz as a preliminary updated value of the absolute frequency of the " f" component for the He-Ne laser international standard at 633 nm.

Optical Frequency Combs: From Frequency Metrology to Optical Phase Control
The merging of continuous wave laser-based precision optical-frequency metrology with mode-locked ultrafast lasers has led to precision control of the visible and near-infrared frequency spectrum produced by mode-locked lasers. Such a phase-controlled mode-locked laser forms the foundation of a “femtosecond optical-frequency comb generator” with a regular comb of sharp lines with well-defined f...
متن کاملMode-resolved frequency comb interferometry for high-accuracy long distance measurement
Optical frequency combs have developed into powerful tools for distance metrology. In this paper we demonstrate absolute long distance measurement using a single femtosecond frequency comb laser as a multi-wavelength source. By applying a high-resolution spectrometer based on a virtually imaged phased array, the frequency comb modes are resolved spectrally to the level of an individual mode. Ha...
متن کاملColloquium: Femtosecond optical frequency combs
Recently there has been a remarkable synergy between the technologies of precision laser stabilization and mode-locked ultrafast lasers. This has resulted in control of the frequency spectrum produced by mode-locked lasers, which consists of a regular comb of sharp lines. Thus such a controlled mode-locked laser is a ‘‘femtosecond optical frequency comb generator.’’ For a sufficiently broad com...

The absolute frequency of an iodine-stabilized He−Ne laser at 633 nm stabilized on the i (or a13) component of the 11-5 R(127) hyperfine transition of the I2 molecule is measured using a femtosecond optical comb generator and an iodine-stabilized Nd:YAG laser standard at 1064 nm. We link the measured absolute frequency to the current internationally adopted value via frequency intercomparison b...
متن کاملGeneration of Ultra Low Phase Noise Microwave Local Oscillators from Optical Frequency Standards Using Femtosecond Laser Synthesis
The development of ultra stable femtosecond laser comb generators is resulting in the emergence of a method to transfer the fundamentally higher stability of optical frequency standards and oscillators to microwave frequency outputs. This is important for applications where coherent signal generation and reception is used e.g. Radar or Electronic Defence. The stability an...
