“…4, curve 4). The crystallization medium prepared in the above way preserves its properties for many days, at temperatures 780-760 1C (onset of crystallization) included, which is particularly important for growing large single crystals under the low-gradient thermal conditions of Kyropoulos method and its variants [12].…”

“…Recently, LBO crystals were characterized by record bulk damage threshold, 45GW/cm 2 at λ=1.064µm, 1.1ns pulse width, among inorganic frequency conversion crystals [3]. Nowadays the growth of high quality LBO crystals with weight of near 300g and up to 10cm in size is feasible that permits the formation of nonlinear optical elements as long as 25mm in some phase-matching directions without crossing growth sector boundaries [4]. The fundamental electronic structure and mechanism of nonlinear optical effects in LBO, commonly in comparison with other nonlinear optical borates, have been theoretically investigated in numerous works [5][6][7][8][9][10][11][12].…”

The electronic and structural properties of LiB 3 O 5 (LBO) surfaces have been studied by X-ray photoemission spectroscopy (XPS) and reflectance high-energy electron diffraction (RHEED). The as-grown (110) crystal face and mechanically polished (001) surfaces have been investigated comparatively. Electronic structure of LBO has been determined on as-grown (110) crystal face previously cleaned by chemical etching with RHEED control. The correlation of valence band structure and measured binding energies with earlier reported results has been discussed. Core-level spectroscopy reveals strong enriching of mechanically polished LBO surface with carbon, when nanodiamond powder is used as an abrasive. So high carbon level as C:B=0.7 has been observed at the surface while the ratio Li:B:O remains according to LBO chemical composition. The association of LBO Kikuchi-lines with strong background has been shown by RHEED analysis of the surface. Thus, the polished LBO surface constitutes a high structure quality LBO with the inclusions of some amorphous carbon compound.

“…Idler absorption becomes an important issue in designing parametric devices above 2.5 µm in oxide materials such as β-BaB 2 O 4 (BBO) [15], LiB 3 O 5 (LBO) [16], and above 4 µm in LiNbO 3 , LiTaO 3 , and in KTiOPO 4 (KTP) isomorphs [17]. Example of a transmission spectrum in 10 mm-thick KTP and RbTiOAsO 4 (RTA) for light polarized parallel to the crystal z-axis is shown in Fig.…”
