摘要

我们介绍了定位光学频率梳固定点的改进方法。两个连续波激光器被锁定到一个参考频率梳状器上，并在相隔约 1.6 太赫兹的两个点跟踪第二个被测梳状器 (CUT) 的光学相位。载波包络和光学相位跟踪（OPT）可在泵浦调制频率（400 Hz-250 kHz）范围内实现精确的定点测量。可以观察到固定点亚纳米级的移动。使用双梳干涉测量法（DCI）也能高精度地确定定点，其值与双点跟踪法的计算结果非常接近。

Mode-resolved optical frequency comb fixed point localization via dual-comb interferometry.

We describe improved methods for locating the fixed point of an optical frequency comb. Two continuous-wave lasers are locked to a reference frequency comb and track the optical phase of a second comb-under-test (CUT) at two points separated by approximately 1.6 THz. Carrier-envelope and optical phase tracking (OPT) yields a precise fixed point measurement across a range of pump modulation frequencies (400 Hz-250 kHz). Sub-nanometer shifts of the fixed point are observed. The fixed point is also determined with high precision using dual-comb interferometry (DCI), and the value closely matches the calculation from the dual-point tracking method.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
