Optimization of terahertz wave generation from nonlinear optical crystal using amorphous fluoropolymer coating

The amorphous fluoropolymer Cytop
^TM
is a coating material for organic nonlinear optical crystals. As a coating material, it acts as both an antireflection coating and a protective layer for the crystal itself in advanced terahertz (THz) wave generation applications. In this study, we report on the optical parameter in THz frequency over a wide temperature ranges, and the optimization of THz wave generation from a Cytop-coated nonlinear optical crystal.
