Kind Code:
B2
Abstract:
[Object] An optimal structure for spectroscopically analyzing a solid-phase or liquid-phase sample in a wavelength range of 1100 to 1200 nm by using supercontinuum light is provided.[Solution] Supercontinuum light generated by producing nonlinear effects in light from a pulse laser source 1 by a nonlinear element 2 and having a wavelength range including 1100 nm or greater and 1200 nm or less is subjected to pulse stretching by a pulse stretching element 3, and a solid-phase or a liquid-phase sample S is irradiated with the supercontinuum light. In the supercontinuum light, elapsed time and wavelength within one pulse are in a one-to-one correspondence, and computation means 5 computes a spectrum based on a change over time in an output from a light receiver 4 that has received light that has passed through the sample S.
