Journal ArticleDOI
High-speed molecular spectral imaging of tissue with stimulated Raman scattering
Yasuyuki Ozeki,Yasuyuki Ozeki,Wataru Umemura,Yoichi Otsuka,Shuya Satoh,Hiroyuki Hashimoto,Kazuhiko Sumimura,Norihiko Nishizawa,Kiichi Fukui,Kazuyoshi Itoh +9 more
TL;DR: In this article, a label-free scheme was proposed for video-rate imaging of various types of biological tissue using stimulated Raman scattering microscopy, which offers molecular specificity and frame-by-frame wavelength tunability allowing the creation of 2D and 3D images of samples showing different constituents.
Journal ArticleDOI
Compact system of wavelength-tunable femtosecond soliton pulse generation using optical fibers
Norihiko Nishizawa,Toshio Goto +1 more
TL;DR: In this paper, the authors proposed a system of wavelength-tunable femtosecond (fs) fundamental soliton pulse generation with a monocolored soliton, not multicolored ones, with the ideal sech/sup 2/shape.
Journal ArticleDOI
Flatly broadened, wideband and low noise supercontinuum generation in highly nonlinear hybrid fiber
TL;DR: Wideband of 1180-2100 nm, flatly broadened supercontinuum (SC) generation using highly nonlinear hybrid fibers and femtosecond fiber laser is presented.
Journal ArticleDOI
High-resolution time-of-flight terahertz tomography using a femtosecond fiber laser
Jun Takayanagi,Hiroki Jinno,Shingo Ichino,Koji Suizu,Masatsugu Yamashita,Toshihiko Ouchi,Shintaro Kasai,Hideyuki Ohtake,Hirohisa Uchida,Norihiko Nishizawa,Kodo Kawase +10 more
TL;DR: To the authors' knowledge, this is the first demonstration of terahertz tomographic imaging of such a thin layer, using a reflection-type terAhertz time-domain spectroscopy using a robust all-fiber laser.
Journal ArticleDOI
All-polarization-maintaining Er-doped ultrashort-pulse fiber laser using carbon nanotube saturable absorber.
Norihiko Nishizawa,Y. Seno,Kazuhiko Sumimura,Youichi Sakakibara,E. Itoga,Hiromichi Kataura,Kazuyoshi Itoh +6 more
TL;DR: An all-polarization-maintaining Er-doped ultrashort-pulse fiber laser using a single-wall carbon nanotube polyimide nanocomposite saturable absorber is presented and it is confirmed that the noise figure is as low as that of a solid-state laser.
