YAl3(BO3)4: Crystal growth and characterization

Crystal growth and optical properties of YAl3(BO3)4 for UV applications

“…There are two borate flux systems which can grow YAB crystals with relatively low UV absorption so far, the Al 2 O 3 -Li 2 O-B 2 O 3 flux system [11] and the Li 2 O-B 2 O 3 flux system [15]. The earlier reported Al 2 O 3 -Li 2 O-B 2 O 3 flux system was chosen in our experiments and it was proved suitable for YAB crystal growth.…”

“…2(a). In the Li 2 O-B 2 O 3 flux system, the cooling range is limited to 30 1C, otherwise the melt will become turbid [15].…”

“…The fourth harmonic generation of an Nd-based laser at 266 nm with an average power of 5.05 W was obtained, but the extrinsic UV absorption of the crystal still existed, which inhibited gaining higher outputs [14]. Yu et al [15] reported the crystal growth of YAB from the Li 2 O-B 2 O 3 flux system in 2010. A crystal with the dimensions of 16 Â 16 Â 18 mm 3 was obtained.…”

Growth of High Quality Al-Doped CsLiB6O10 Crystals Using Cs2O-Li2O-MoO3 Fluxes

“…Recently, considerable research has been conducted on borate series nonlinear optical crystals for harmonic generation in high-power solid-state ultraviolet (UV) lasers due to their excellent properties such as relatively high tolerance to laser-induced damage, large nonlinear optical coefficients, moderate birefringence, and wide transparency range in the UV region. For instance, several borate crystals, such as β-BaB 2 O 4 (BBO) [4], LiB 3 O 5 (LBO) [5], CsB 3 O 5 (CBO) [6], CsLiB 6 O 10 (CLBO) [7,8], KBe 2 BO 3 F 2 (KBBF) [9], YCa 4 O(BO 3 ) 3 (YCOB) [10], and YA1 3 (BO) 4 (YAB) [11] have attracted a great deal of attention. Among these crystals, CLBO is a newly developed borate crystal and has been successfully applied for the fourth and fifth-harmonic generation of a Nd:YAG laser [12,13].…”

“…Кристаллы алюмоборатов редкоземель-ных элементов используются в качестве эффективных люминофоров, при создании оптических квантовых ге-нераторов, элементов нелинейных оптических систем, эффективных лазеров, а также нелинейных сред для генерации четвертой гармоники излучения неодимового лазера (Nd : YAG) [1][2][3][4].…”
