Background
Nonlinear optical crystals are very important optical functional materials that can extend the limited spectral output range of lasers. With the rapid development of photolithography technology, laser processing and other industries, the requirement for nonlinear optical crystals is growing increasingly, and the development of all-solid-state laser sources has become a domestic and foreign laser sourceOne hotspot in research in the optical field. Due to the transmission band limitation of the crystals, the applicable band of each crystal is different, and the nonlinear optical crystals applicable to ultraviolet and deep ultraviolet bands are fewer. In the ultraviolet band, the industrialized nonlinear optical crystal has LiB 3 O 5 (LBO)、CsB 3 O 5 (CBO)、CsLiB 6 O 10 (CLBO) and Low temperature phase BaB 2 O 4 (beta-BBO) and the like. However, LBO, CBO and CLBO have small birefringence and cannot achieve phase matching in the deep ultraviolet band. And BBO crystals cannot realize phase matching of deep ultraviolet band due to walk-off effect. In the deep ultraviolet band below 200nm, KBe 2 BO 3 F 2 (KBBF) is the only nonlinear optical crystal which can be practically used at present, but the application of the nonlinear optical crystal is limited due to lamellar growth habit and toxic raw materials. Therefore, it is necessary to search for a novel ultraviolet nonlinear optical crystal having more excellent properties.
