“…In particular, the existence of nonlinear absorption may decrease the frequency conversion efficiency, and may even result in internal damage when optical devices are used in a high-power laser system. Therefore, a better understanding of optical properties of crystalline material [16][17][18], especially the nonlinear absorption properties of the BTS crystal, is essential to realize its optical applications.…”

Abstract:In this work, using large-sized single crystals of high optical quality, the optical properties of Ba 2 TiSi 2 O 8 were systematically investigated, including transmission spectra, refractive indices and nonlinear absorption properties. The crystal exhibits a high transmittance (>84%) over a wide wavelength range from 340 to 2500 nm. The refractive indices in the range from 0.31256 to 1.01398 µm were measured, and Sellmeier's equations were fitted by the least squares method. The nonlinear absorption properties were studied by using the open-aperture Z-scan technique, with a nonlinear absorption coefficient measured to be on the order of 0.257 cm/GW at the peak power density of 16.4 GW/cm 2 . Such high transmittance and wide transparency indicate that optical devices using the Ba 2 TiSi 2 O 8 crystal can be applied over a wide wavelength range. Furthermore, the small nonlinear absorption observed in Ba 2 TiSi 2 O 8 will effectively increase the optical conversion efficiency, decreasing the generation of laser damage of the optical device.

In this report, an abnormal optical anisotropy in KTa1−xNbxO3:Cu (Cu:KTN) crystals with refractive index gradient is presented. Contrary to general regulation in a cross-polarization setup, the transmitted intensity of both TE (horizontally polarized) and TM (vertically polarized) lasers aligned with the basic crystallographic directions can be modulated quasiperiodically. The mechanism is supposed to be based on the polarization induced by the temperature gradient and the refractive index gradient. Meanwhile, the correlated disorder property of the crystals in the range of the freezing temperature (Tf) and the intermediate temperature (T *) also plays an important role. With the results verified both theoretically and experimentally, we believe this work is not only beneficial for the development of the theory associated with the correlated disorder structures in relaxor ferroelectrics, but also significant for the exploitation of numerous optical functional devices.
