Nonlinear terahertz-wave radiation generated by mid-infrared dual-chirped optical parametric amplification femtosecond pulse laser excitation
Kyuki Shibuya, Kouji Nawata, Yoshiaki Nakajima +5
We demonstrate an efficient procedure for terahertz-wave radiation generation by applying a nonlinear wavelength conversion approach using a mid-infrared pump source. We used a 3.3…
Lock-in-detection dual-comb spectroscopy
Hidenori Koresawa, Kyuki Shibuya, Takeo Minamikawa +9
Dual-comb spectroscopy (DCS) is useful for gas spectroscopy due to high potential of optical frequency comb (OFC). However, fast Fourier transform (FFT) calculation of a huge amoun…
Multicascade-linked synthetic wavelength digital holography using an optical-comb-referenced frequency synthesizer
Masatomo Yamagiwa, Takeo Minamikawa, Clément Trovato +11
Digital holography (DH) is a promising method for non-contact surface topography because the reconstructed phase image can visualize the nanometer unevenness in a sample. However,…
Refractive-index-sensing radio-frequency comb with intracavity multi-mode interference fibre sensor
Roy Oe, Shuji Taue, Takeo Minamikawa +8
Optical frequency combs have attracted attention as optical frequency rulers due to their tooth-like discrete spectra together with their inherent mode-locking nature and phase-loc…
Dual-optical-comb spectroscopic ellipsometry
Takeo Minamikawa, Yi-Da Hsieh, Kyuki Shibuya +8
Spectroscopic ellipsometry is a means to investigate optical and dielectric material responses. Conventional spectroscopic ellipsometry has trade-offs between spectral accuracy, re…
Scan-less hyperspectral dual-comb single-pixel-imaging in both amplitude and phase
Kyuki Shibuya, Takeo Minamikawa, Yasuhiro Mizutani +4
We have developed a hyperspectral imaging scheme that involves a combination of dual-comb spectroscopy and Hadamard-transform-based single-pixel imaging. The scheme enables us to o…
