Nonlinear Raman spectroscopy, nonlinear Raman spectroscopy system and non-linear Raman spectroscopy method

摘要

PROBLEM TO BE SOLVED: To provide an efficient, stable, and compact non-linear raman spectroscopy apparatus, non-linear raman spectroscopy system, and non-linear raman spectroscopy method.;SOLUTION: A non-linear Raman spectroscopy apparatus includes: a light source unit emitting a pulse beam having a pulse width of 0.2 ns to 10 ns, a pulse peak power of 50 W to 5000 W, and a wavelength of 500 nm to 1200 nm; and a single-mode fiber through which continuous white light is generated from the pulse beam. A test sample to be measured is radiated with a pump-beam-cum-probe beam formed of the pulse beam and a Stokes beam formed of the continuous white light to obtain a Raman spectrum.;COPYRIGHT: (C)2013,JPO&INPIT
