Abstract In the process of terahertz (THz) wave generation via optical rectification of infrared femtosecond pulses in a non-linear optical crystal, the power of terahertz wave is directly proportional to the square of the optical pump power. Therefo

There was no appropriate antireflection coating material for organic nonlinear optical (NLO) crystal used for terahertz wave generation; therefore, it was difficult to reduce Fresnel’s reflection loss of laser power used to excite the emitter cryst

The amorphous fluoropolymer CytopTM 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 generati

We have realized practical antireflection (AR) coatings for organic nonlinear optical crystals via dip coating of soft materials; specifically, the amorphous fluoropolymer Cytop. 4-N, N-dimethylamino-4′-N′-methyl-stilbazolium tosylate (DAST) crys
