Journal ArticleDOI
Three-Dimensional Optical Measurement with Spectroscopic Function Using Fiber Laser Supercontinuum
TL;DR: In this paper, a 3D measurement system with spectroscopic function was demonstrated using a practical supercontinuum light source and an all-fiber interferometer, where the spectral information was obtained by Fourier transformation of the observed interference signal.
Proceedings ArticleDOI
Analysis of wavelength tunable femtosecond soliton pulse generation using pulse width variable fiber laser
TL;DR: In this article, the characteristics of wavelength tunable femtosecond soliton pulse generation were investigated experimentally and numerically and the dependence of conversion efficiency and wavelength shift on the pump pulse was clarified.
Journal ArticleDOI
Evaluation of noise increase due to pump light crosstalk in quadrature squeezed light generation with a fibre ring reflector
TL;DR: In this article, the output noise of the homodyne detector, whose signal light is the squeezed light with non-zero amplitude, is analyzed theoritically and experimentally for the first time.
Journal ArticleDOI
Generation of Squeezed Vacuum using Spectral Filter by Spatial Light Modulator and Nonlinear Polarization Interferometer
TL;DR: In this paper, an optical fiber, spectral filter consisting of the spatial light modulator (SLM), and a nonlinear polarization interferometer (NOPI) was used to suppress the classical amplitude noise and modulate the amplitude and phase of incident pulses simultaneously.
Journal ArticleDOI
Preselecting method for plutonium particle analysis in environmental samples by nuclear emulsion
TL;DR: In this paper, a preselecting method for plutonium particle analysis based on counting of fission tracks and alpha particle tracks in nuclear emulsion was proposed, which is able to classify sample into three grades, i.e., weapon-grade, fuel-grade and reactor-grade.
