Abstract
A pumping beam L1 enters from a pumping beam projector 3 into one end surface 2a of a nonlinear crystal 2, the pumping beam L1 and idler wave L2 are generated from another end surface 2b of the nonlinear crystal 2. The pumping beam L1 emitted from the other end surface 2b of the nonlinear crystal 2 is reflected and re-enters as a pumping beam L′ into the other end surface 2b and the idler wave L2 generated from the other end surface 2b of the nonlinear crystal is reflected by the reflection optical system 6 and re-enters as a seed beam L2′ into the other end surface 2b. The idler wave L2 enters as the seed beam L2′ together with the pumping beam L1′ into the nonlinear crystal and thus a terahertz wave with a large output and including a plurality of wavelengths can be generated.
