Cs2AlB5O10: a short-wavelength nonlinear optical crystal with moderate second harmonic generation response†
Abstract
A new compound Cs2AlB5O10 was synthesized by a high temperature solution method in open air. It features a DUV cutoff edge below 190 nm and a moderate SHG response (0.8 × KDP at 1064 nm), indicating that it may have certain application prospects in the UV nonlinear optical region.
