A promising ultraviolet nonlinear optical crystal: Rb₃Ba₃Li₂Al₄B₆O₂₀F—crystal growth, physical properties, and 266 nm laser generation

Abstract

Ultraviolet laser is an indispensable technology applied in the fields of photolithography, micromachining and laser prototyping. Up to now, only β-BaB2O4 and CsLiB6O10 are commercially available for direct fourth harmonic...

Recent advances in rational structure design for nonlinear optical crystals: leveraging advantageous templates

“…(Fig. 7f) Recently, Pan et al (2022) 91 and Yu et al (2023) 92 successfully achieved 266 nm light generation through direct FHG of the Nd: YAG laser using K 3 Sr 3 Li 2 Al 4 B 6 O 20 F and Rb 3 Ba 3 Li 2 Al 4 B 6 O 20 F crystals (Fig. 7e).…”

Li3Na7B4P6O26: a new ultraviolet transparent congruently melting non-linear optical crystal

“…Deep ultraviolet (DUV) coherent lights produced by solid-state lasers 1–5 have many important applications in high-tech fields such as laser processing, advanced manufacturing, and information storage. 6–10 Nonlinear optical (NLO) crystals 11,12 are indispensable for solid-state lasers to output the DUV laser because the solid-state lasers cannot produce the DUV laser through direct lasing; 13 on the contrary, the use of the cascaded second harmonic generation (SHG) is the best way for the solid state lasers to output the DUV lasers.…”
