Abstract
A pumping beam Lis caused to be incident on an end surfaceA of a nonlinear crystal, and a seed beam L, the diameter of which is increased by a concave lens, is collected and adjusted into a collimated beam by a convex lensand caused to be incident on the end surfaceA described above. The pumping beam Land the seed beam Lare caused to be incident on the end surfaceA with the pumping beam Land the seed beam Lsuperimposed on each other, whereby the nonlinear crystalgenerates a terahertz wave TH.
