Binary rare-earth scandium borates for diode-pumped lasers

Gd La1−Sc3(BO3)4: A new nonlinear optical crystal

“…Binary borates with a general chemical formula RM 3 (BO 3 ) 4 in the trigonal huntite-type structure have received much attention during the past four decades [1,2]. Particular interest in these materials arises from their potential applications in nonlinear optics and laser engineering [3][4][5][6][7].…”

Photoluminescence characteristics of β-BaB2O4 nanoparticles co-doped with Cu2+ and Pb2+

“…Among them, ␤-BaB 2 O 4 is of great technological interesting because of its attractive properties as wide transparent wave band, low linear absorption and high damage threshold [4][5][6]. Many efforts have been made to apply it in non-linear devices for ultraviolet solid-state laser.…”

A new promising nonlinear optical (NLO) crystal for visible and ultraviolet (UV) regions

“…Experimental results show that borate type compounds constitute a veritable source of NLO crystals with good nonlinear properties [7,8]. Therefore, all the recent NLO crystals discovered in the last 10 years are in majority borate based compounds such as: CsLiB 6 O 10 (CLBO), BiB 3 O 6 (BiBO), K 2 Al 2 B 2 O 7 (KABO), KBe 2 BO 3 F 2 (KBBF), ReCa 4 O(BO 3 ) 3 (Re = Gd, Y, La) -ReCOB [7][8][9][10][11][12][13], LnSc 3 (BO 3 ) 4 (Ln = lanthanide) [14,15], etc. Nowadays, two families of borate crystals are known that melt congruently or comprise congruently melting compounds, which can be grown in large sizes by the Czochralski method: the family of rare-earth calcium oxyborates with chemical composition ReCa 4 O(BO 3 ) 4 (Re being a rare -earth ion, usually Gd, Y or La) [16,17], and the family of LnSc 3 (BO 3 ) 4 borates.…”
