Structural study of LiKB4O7 and LiRbB4O7: New nonlinear optical crystals

Kerr and Faraday effects in borate glasses

“…where 11 R and 12 R are the components of a fourth-rank polar tensor describing the Kerr effect. While studying experimentally the Kerr effect, we used the same setup depicted in Fig.…”

“…Non-centrosymmetric representatives of this family are efficient nonlinear optical materials [2,5,[6][7][8][9][10][11] and also manifest high optical resistance [12]. They are widely used in parametric optical oscillators as functional elements [13,14].…”

Crystal Growth and Associated Properties of a Nonlinear Optical Crystal—Ba2Zn(BO3)2

“…The intense research on the NLO phenomena of borates was triggered by the second-harmonic generation (SHG) reported on β-BaB 2 O 4 (β-BBO) and LiB 3 O 5 (LBO) in the late 1980s [7,8]. Thereafter, a variety of NLO borate materials have been discovered, such as BaZn 2 (BO 3 ) 2 [9], CsB 3 O 5 (CBO) [10], Ba 2 Zn(BO 3 ) 2 [11], KBe 2 BO 3 F 2 (KBBF) [12], Sr 2 Be 2 B 2 O 7 (SBBO) [13], CsLiB 6 O 10 (CLBO) [14], K 2 Al 2 B 2 O 7 (KABO) [15], BaAl 2 B 2 O 7 (BABO) [15], LiAB 4 O 7 (A = K, Rb) [16], M 2 B 5 O 9 X (M = Pb, Ca, Sr, Ba; X = Cl, Br) [17], MBi 2 B 2 O 7 (M = Ca, Sr) [18], Ca 5 (BO 3 ) 3 F [19], BiAlGa 2 (BO 3 ) 4 [20], Bi 2 ZnOB 2 O 6 [21], Ba 3 Sr 4 (BO 3 ) 3 F 5 [22], BaMBO 3 F (M = Zn, Mg) [23], M 3 B 6 O 11 F 2 (M = Sr, Ba) [24], K 3 [33], Li 4 Sr(BO 3 ) 2 [34] and K 3 Ba 3 Li 2 Al 4 B 6 O 20 F [35]. Despite these new borate-based NLO materials, β-BBO, LBO and CLBO are still the most frequently used NLO crystals in UV region, which is attributable to the difficulties of growing high quality crystals or the low transmittance in the UV region.…”

Acoustooptic and acoustic properties of KLiB4O7 crystals

“…A wide range of their optical transparency, particularly in the ultraviolet region [15][16][17][18][19] (up to 125 nm for 4 7 SrB O [18, 19]), and a high level of optical damage threshold [19,20] make them attractive for optoelectronics. 4 7 KLiB O crystals abbreviated hereafter as KLTB are grown by using isovalent substitution of half of Li atoms by K ones in the initial 2 4 7 Li B O compound [21,22]. At the room temperature KLTB belongs to the acentric point group of symmetry 222 [21,22], the lattice parameters being 8.4915A a = , 11.1415A b = and 12.6558A c = [22].…”
