Recent development of nonlinear optical borate crystals: key materials for generation of visible and UV light

Abstract The development of nonlinear optical (NLO) borate crystals for generation of visible and UV light is reviewed. We first discussed on the basic principles of laser frequency conversion. Then, we examine the trends in research on NLO crystals. The background and present status of NLO borate crystals are summarized. The main considerations are focused on the discussion of crystals like CsLiB 6 O 10 (CLBO), Gd x Y 1− x Ca 4 O(BO 3 ) 3 (GdYCOB) and K 2 Al 2 B 2 O 7 (KAB). Properties of related materials like β-BaB 2 O 2 (BBO), LiB 3 O 5 (LBO), KBe 2 BO 3 F 2 (KBBF), Sr 2 Be 2 BO 7 (SBBO), CsB 3 O 5 (CBO), GdCa 4 O(BO 3 ) 3 (GdCOB) and YCa 4 O(BO 3 ) 3 (YCOB) are included for comparison. We aim to provide a complete view of developing a new NLO borate material for actual laser applications. This review covers various aspects including the search for new materials, the growth of bulk crystals, the characterization of crystal properties as well as the development of new techniques to overcome obstacles in actual laser application, namely, thermal dephasing and laser-induced damage. Finally, perspectives on NLO borate crystals and all-solid-state UV lasers are evaluated.
