Ultra-precise determination of thicknesses and refractive indices of optically thick dispersive materials by dual-comb spectroscopy

Kana A. Sumihara, Sho Okubo, Makoto Okano +2

Precise measurements of the geometrical thickness of a sample and its refractive index are important for materials science, engineering, and medical diagnosis. Among the possible n…

Dual-comb cavity ring-down spectroscopy

D. Lisak, D. Charczun, A. Nishiyama +10

Cavity ring-down spectroscopy is a ubiquitous optical method used to study light-matter interactions with high resolution, sensitivity and accuracy. However, it has never been perf…

Ultra-broadband dual-comb spectroscopy across 1.0-1.9 μm

Sho Okubo, Kana Iwakuni, Hajime Inaba +4

We have carried out dual-comb spectroscopy and observed in a simultaneous acquisition a 140-THz-wide spectrum from 1.0 to 1.9 μm using two fiber-based frequency combs phase-locked…

Generation of incoherent light from a laser diode based on the injection of an emission from a superluminescent diode

Akifumi Takamizawa, Shinya Yanagimachi, Takeshi Ikegami

In this study, incoherent light with a spectral linewidth of 7 nm and 140 mW of power was generated from a laser diode into which incoherent light emitted from a superluminescent d…

Gapless dual-comb spectroscopy in terahertz region

Takeshi Yasui, Yi-Da Hsieh, Yuki Iyonaga +6

We demonstrated combination of gapless terahertz (THz) comb with dual-comb spectroscopy, namely gapless dual-THz-comb spectroscopy, to achieve the spectral resolution equal to widt…
