光ファイバの誘導ラマン散乱を利用した連続スペクトル光の発生 Generation of Spectrally Continuum Light by Stimulated Raman Scattering in Optical Fiber
The operational characteristics of an ultra-broadband light source using the stimulated Raman scattering in a single-mode optical fiber for the application to optical coherence tomography is described. The ultra-broadband output light covering from 770 nm to 1650 nm was obtained using a 500-m-long single-mode phosphorus-doped Si0<SUB>2</SUB> optical fiber pumped by a self Q-switched Ti: sapphire laser with a spectral width of 13 nm. When a white-light Michelson interferometer was constructed using the fiber Raman laser as a light source, a longitudinal spatial resolution of 1.7 μm was achieved.
