摘要：

We demonstrate rapid characterization of complex optical properties of solids via dual-comb spectroscopy (DCS) in the near- infrared region. The fine spectral structures in the complex refractive index of an Er:YAG are successfully deduced using the developed system and Fourier analysis. Moreover, simultaneous determination of the refractive index and the thickness is demonstrated for a silicon semiconductor wafer through the use of multireflected echo signals. The results indicate the potential of DCS as a powerful measurement tool for the rapid and full characterization of solid materials. (C) 2016 Optical Society of America
