Abstract

We developed a difference frequency generation (DFG) source with an organic nonlinear optical crystal of DAST or BNA selectively excited by a dual-wavelength β-BaB2O4 optical parametric oscillator (BBO-OPO). The dual-wavelength BBO-OPO can independently oscillate two lights with different wavelengths from 800 to 1800 nm in a cavity. THz-wave generation by using each organic crystal covers ultrawide range from 1 to 30 THz with inherent intensity dips by crystal absorption modes. The reduced outputs can be improved by switching over the crystals with adequately tuned pump wavelengths of the BBO-OPO.

Pulse energies and spectral bandwidths of idler waves from the dual-wavelength BBO-OPO as a function of oscillation wavelengths. Here, the pulse energy is sum of dual-wavelength lights whose wavelengths were same. A pump pulse energy of 355-nm light was 30 mJ.

Example of spectrum power balance of dual-wavelength. For example, a power difference between 1.3 and 1.5 μm which correspond to 30 THz photon energy is roughly 2dB. The level of the power balance degradation in our dual-wavelength BBO-OPO is in tolerance for THz-wave generation.

Prospective THz-wave spectrum when DAST- and BNA-DFG are combined. If many other organic crystals are used, higher and wider THz-wave spectrum can be obtained. The developed dual-wavelength BBO-OPO can be applied to almost all organic nonlinear materials.
