“…The measurement results obtained at room temperature are presented in Figure 4. The optical properties agree well with the previous measurements obtained by our team [28,29] and recent results from other groups [30,31]. The only discrepancy in the results is the axis labeling, which was discussed earlier [28].…”

“…The optical properties agree well with the previous measurements obtained by our team [28,29] and recent results from other groups [30,31]. The only discrepancy in the results is the axis labeling, which was discussed earlier [28]. The shorter spectral range of the yand x-axes is explained by the higher LBO absorption of these axes and the lower dynamic range of the spectrometer at higher frequencies.…”

We propose a method for measuring the terahertz properties for two principal optical axes of anisotropic crystals without optical activity using terahertz time-domain spectroscopy (THz-TDS). The method put forward in this paper utilizes the inherent polarization sensitivity of the THz-TDS electro-optic detection system. We demonstrate the practical application of the method by measuring the temperature dependence of the refractive index and the absorption coefficient of a lithium triborate crystal for three optical axes.

“…The properties of LBO in the infrared and far infrared regions above 100 cm −1 (3 THz) have been studied by Raman and infrared reflection spectroscopy 20–23 . However, the optical properties of LBO crystal in the terahertz range have not been fully characterized and systematically studied, especially for different temperatures 24–27 .…”

Optical properties of lithium triborate (LBO) in the terahertz regime (0.2–2 THz) were characterized using broadband terahertz time-domain spectroscopy. The frequency dependence of refractive index and absorption coefficient of the LBO crystal was experimentally investigated over the temperature range of 77–297 K, which the experimental results indicated that LBO has very low optical absorption coefficient at terahertz frequencies especially for the beam polarization along the crystal’s principal dielectric axis X. Moreover, a giant birefringence was observed, and the refractive index difference between the axis X and Z gradually decreased with decreasing temperature, which is attributed to the behavior of the TO phonon modes of B1 and B2 symmetries at low frequencies at different temperatures. As potential applications, LBO can be exemplarily used as terahertz wave shapers, beam splitters, terahertz wave plates, circular polarizers and other polarization devices.

“…Recently these crystals attracted attention as prospective materials for terahertz applications. Several studies were devoted to measuring their optical properties (refractive index and absorption coefficient) in the terahertz domain [2][3][4][5]. Different schemes for IRto-THz and THz-to-THz conversion were investigated [6][7][8][9].…”
