Abstract
A pumping beam L1 is caused to be incident on an end surface 4A of a nonlinear crystal 4, and a seed beam L2, the diameter of which is increased by a concave lens 6, is collected and adjusted into a collimated beam by a convex lens 7 and caused to be incident on the end surface 4A described above. The pumping beam L1 and the seed beam L2 are caused to be incident on the end surface 4A with the pumping beam L1 and the seed beam L2 superimposed on each other, whereby the nonlinear crystal 4 generates a terahertz wave TH.
