Polar Lithium l-Aspartate Monohydrate: A Semiorganic Ultraviolet Transparent Nonlinear Optical Crystal.

Ultraviolet (UV) nonlinear optical (NLO) crystals capable of expanding common laser sources to the UV regime are core components of solid-state lasers. Currently, exploring UV NLO crystals in hybrid organic-inorganic systems is receiving increasing attention. Herein, we report the synthesis, characterization, and linear and NLO properties of a semiorganic UV NLO crystal, namely, lithium l-aspartate monohydrate, Li(L-OOCNHCHCHCOO)·HO ().
