Abstract（报告摘要）:

Optical frequency comb can be used as a tool for high-precision and versatile control of properties of light wave as an “optical synthesizer”. It provides powerful tools not only in frequency metrology as “ultraprecise frequency ruler” but also in broad area since light wave can be used to its full extent with an extremely wide dynamic range. In this lecture, after introducing the development of fiber-based frequency combs, various metrology applications are presented including dual-comb spectroscopy of gas and solid, high-accuracy and long distance measurement with self-correction of air refractive index, and one-shot 3D imaging. By precisely controlling the frequency and phase of the combs, metrology applications with ultra-high accuracy together with ultra-wide dynamic range and versatile controllability are realized.
