Growth of a new nonlinear optical crystal—BaAlBO3F2

Self-organized homo-epitaxial growth in nonlinear optical BaAlBO3F2 crystal crossing lines patterned by laser in glass

“…(1) BaAlBO 3 F 2 is an excellent candidate for high power ultra-violet (UV) solid state laser because of its high second and third harmonic optical nonlinearities, deep UV absorption edge, and high thresholds for laser-induced damage [29][30][31][32][33][34]. (2) BaAlBO 3 F 2 crystals are formed easily in 50BaF 2 -25Al 2 O 3 -25B 2 O 3 glass corresponding to the stoichiometric composition of BaAlBO 3 F 2 by heat treatment in an electric furnace, In order to clarify the orientation state of BaAlBO 3 F 2 crystals at the crossing, bending, and curved points in laser-patterned lines, we also need to select good experimental techniques.…”

Flux growth of BaAlBO3F2 crystals

“…Since BABF melts incongruently, flux growth is a suitable method to obtain high quality crystal. Growth of BABF crystal from NaF flux system was reported by Hu et al [5] in 2002. Recently, some other authors reported that they got crystals using NaF flux system [6,7].…”

Growth and characterization of Ba(Al,Ga)BO3F2 crystal

“…The crystal growth was initiated by a decrease in the solution temperature. Pure BABF crystals were used as seed crystals, and the middle-seeded solution growth technology was adopted precisely the same as that utilized in the crystal growth of BABF [1,2]. The cooling rate was set in the range of 0.2-5 1C/d from the saturation temperature and the rotation speed was set between 20-40 rpm with inversion after every 2 min.…”

“…In 2002, Hu et al [1,2] reported that the BABF belongs to the space group of P6 with cell parameters a¼4.8879 (6) A, c¼9.403(1)Å and Z ¼2. In 2009, Huang et al [3,4] suggested that the space group of BABF should be P6 2c instead of P6 as was reported previously.…”
