Barium Nitrate (Ba(NO3)2) single crystals exhibit optical properties that make them well-suited for use in Raman shifting and related laser applications. These properties include:
- Optical transmission across a broad range from 350 to 1800 nm
- Large Raman shift of 1047 cm-1 toward longer wavelengths
- High quantum conversion efficiency for first and second Stokes components
Applications include the efficient generation of 1.53 µm eye-safe wavelengths.
