Barium Nitrate (BN) Raman Crystals
Barium Nitrate monocrystals are one of the best solid state materials for shifting the emission frequency of lasers to different spectral region using Stimulated Raman Scattering effect.
The Raicol advanced crystal growing technique based on the water solution method yields large transparent BN crystals.
