PROBLEM TO BE SOLVED: To provide a highly accurate, compact, and lightweight spectroscopic apparatus and its a spectroscopic method. SOLUTION: A pumping light obtained by spectrally separating laser light emitted from a laser light source 2, and probe lights L4 and L5 outputted by a pare-wavelength converting device 7 while wavelength-converting laser light L3 emitted from a laser oscillator 2, are used as measuring light.
