Growth and characterization of nonlinear optical borate crystals CsLiB6O10, CsB3O5, and BaAlBO3F2

Abstract Nonlinear optical borate crystals CsLiB6O10, CsB3O5, and BaAlBO3F2 were developed by present authors. They possess superior optical properties desirable for ultraviolet light generation. CsLiB6O10 is suitable for the fourth and fifth harmonic generation of a Nd:YAG laser. CsB3O5 is applicable to the third harmonic generation of a Nd:YAG laser. BaAlBO3F2 is relatively new crystal recognized as a nonlinear optical material. In this paper, we briefly review the recent progress in growing CsLiB6O10 and CsB3O5, and report the growth and characterization of BaAlBO3F2.
