Novel Non-Linear Optical Material for Solid-State Lasers
Our researchers have synthesized three novel non-linear optical crystals, K3Sr3Li2Al4B6O20F, Rb3Ba3Li2Al4B6O20F, and KSrCO3F, for usage in solid-state lasers. All three crystals are capable of coherent radiation at 266 nm, which is a desired wavelength for Nd-YAG solid-state lasers. The crystals are grown using the top seed solution growth (TSSG) method and are able to form large crystals suitable for use in solid-state lasers. The three crystalline materials exhibit excellent optical quality with moderate birefringence, large phase-matching wavelength range, and wide transparency range.
