Journal ArticleDOI
Real-time, ultrahigh-resolution, optical coherence tomography with an all-fiber, femtosecond fiber laser continuum at 1.5 µm
TL;DR: Real-time, ultrahigh-resolution optical coherence tomography (OCT) is demonstrated in the 1.4-microm wavelength region with a stretched-pulse, passively mode-locked, Er-doped fiber laser and highly nonlinear fiber.
Journal ArticleDOI
Experimental and numerical analysis of widely broadened supercontinuum generation in highly nonlinear dispersion-shifted fiber with a femtosecond pulse
TL;DR: In this article, the authors report the analysis of ultrawideband supercontinuum generation in a highly nonlinear dispersion-shifted fiber, where a >1000-nm-spanning white-light continuum is generated by pumping the femtosecond fiber laser pulse at the extreme vicinity of the zero-dispersion wavelength of the fiber.
Journal ArticleDOI
Pulse trapping by ultrashort soliton pulses in optical fibers across zero-dispersion wavelength
Norihiko Nishizawa,Toshio Goto +1 more
TL;DR: Almost perfect conversion efficiencies are observed for soliton self-frequency shift and pulse trapping by the ultrashort soliton pulse of an optical fiber.
Proceedings ArticleDOI
Ultrahigh resolution optical coherence tomography
TL;DR: In this article, a supercontinuum-based optical coherence tomography (OCT) was used for biomedical tissue and materials imaging, where low noise, Gaussian-like supercontinua were generated at five wavelength regions.
Journal ArticleDOI
Stimulated Raman scattering microscope with shot noise limited sensitivity using subharmonically synchronized laser pulses
Yasuyuki Ozeki,Y. Kitagawa,Kazuhiko Sumimura,Norihiko Nishizawa,Wataru Umemura,Shin'ichiro Kajiyama,Kiichi Fukui,Kazuyoshi Itoh +7 more
TL;DR: Subharmonically synchronized laser pulses are proposed and demonstrated for low-noise lock-in detection in stimulated Raman scattering (SRS) microscopy and high-contrast, 3D imaging of unlabeled living cells.
