We present the spectra of the refractive index and the absorption coefficient of BiB3O6 (BIBO) crystal measured by the means of terahertz time-domain spectroscopy in the frequency range of 0.18–2.75 THz. We observe a large birefringence Δn = nZ − nX = 1.5 and the values of absorption coefficients of all three axes to be less than 5 cm−1 in the range below 1 THz. We report weak absorption lines in the vicinity of 2.28 and 2.6 THz for the Z-axis. Our results show that at room temperature BIBO has a lower absorption than other popular oxygen-containing nonlinear crystals: β–BBO, LBO, KTP, and LN. Thus, we assume the crystal to be an efficient THz radiation generator under intense laser pumping. |
