Abstract: Abstract A high-efficiency terahertz (THz) wave amplification approach by coupled cascaded optical parametric processes (CCOPP) with orientationally patterned gallium phosphide (OP-GaP) is introduced. The CCOPP comprises two cascaded optical parametric processes (COPP) which are intensely… read more here.
