摘要： PROBLEM TO BE SOLVED: To achieve a terahertz wave-generating device which can easily constitute a spectroscopic device.
SOLUTION: Signal light from a signal light source 10 and pump light from a pump light source 11 are multiplexed by a nonpolarization beam splitter 12 to generate multiplexed light, and the multiplexed light is amplified by a fiber amplifier. Then, the multiplexed light is divided into multiplexed light (A) and multiplexed light (B) by a polarization beam splitter 15, and the multiplexed light (A) and the multiplexed light (B) are mixed by a polarization beam splitter 16 so that they may overlap in a GaP crystal 17 with a phase matching angle which they form. By this, the terahertz wave by the difference frequency mixing of the pump light in the multiplexed light (B) with the signal light in the multiplexed light (A) and the terahertz wave by the difference frequency mixing of the pump light in the multiplexed light (A) with the signal light in the multiplexed light (B) are radiated in two directions. One of the terahertz waves radiated in the two directions can be the reference light, and accordingly a spectroscopic device can easily be constituted.
