Frequency doubling and tuning with KB5O8·4H2O and application to NO (A2Σ+) excitation

Abstract Frequency doubling by angle tuning with KB 5 O 8 ·4H 2 O has been investigated at 217.0–250 nm. The phase matching angle, refractive index and doubling efficiency have been measured. A first application has been made by exciting NO(A 2 Σ + ) in the UV.
