Abstract

We present a detailed study of the dielectric constant and loss tangent of popular nonlinear optical crystals LBO, β-BBO, and KTP in the range of 0.6-1.5 mm (200-500 GHz) at room and liquid nitrogen (77 K) temperatures. These materials have a strong commercial influence as nonlinear frequency converters of laser radiation in the visible and near-infrared spectra, but the prospects for millimeter-wave photonics and optoelectronics applications are still unclear. Besides, the phase-matching curves for DFG of 1.064 μm laser radiation into millimeter waves were numerically estimated to show the feasibility of using the crystals as compact intense radiation sources.
