摘要： PROBLEM TO BE SOLVED: To make it possible to attain high Raman conversion efficiency without the increase in size and complication by making the optical axis of the light passing a first resonator back and forth and the optical axis of the light passing a second resonator back and forth coaxial. SOLUTION: The exciting laser beam resonator 16 comprises a reflection mirror 12 for reflecting the exciting laser beam and a reflection mirror 14 for reflection the exciting laser beam and emitting Stokes light. The resonator 20 for Stokes light comprises a reflection mirror 18 for allowing the transmission of the exciting laser beam and reflecting the Stokes light existing therebetween and the reflection mirror 14 for reflecting the exciting laser beam and emitting the Stokes light. A TEA-CO2 laser 22 is arranged between the reflection mirror 12 and reflection mirror 18 in the resonator 16. The reflection mirror 18 and the reflection mirror 14 are fitted to both end faces of a Raman cell 26 in such a manner that the inside thereof is hermetically sealed. Para-hydrogen is (p-H2 ) is fitted in the Raman cell 26. The optical axis of the exciting laser beam passing the inside of the resonator 16 back and forth and the optical axis of the Stokes light passing the inside of the resonator 20 back and forth are aligned.

摘要： PROBLEM TO BE SOLVED: To provide a spectral analysis system with high resolution and sensitivity that sweeps wavelength in a wide wavelength area by a single system and easily calibrates the wavelength. SOLUTION: The spectral analysis system includes a laser resonator composed of a facing mirror with predetermined reflection factor, a variable wavelength laser medium arranged in the laser resonator oscillating an laser in a wavelength area in a predetermined range, a photoacoustic optical crystal arranged in the laser resonator where exiting light from the variable wavelength laser medium is entered, an acoustic wave inputting means mounting on the photoacoustic optical crystal for inputting an acoustic wave to photoacoustic optical crystal, an excitation laser entering excitation laser light into the laser resonator, and a spectral means entering exiting laser light with a continuous spectrum from the laser resonator to perform spectrum decomposition of the exiting laser light with prescribed resolution.
