Overview
Barium Nitrate (Ba(NO3)2)
Barium Nitrate 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 1,800 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.

Size & Orientation
Available in cross sections up to 10 x 10 mm and lengths up to 75 mm, Barium Nitrate crystals are typically oriented, finished and coated as follows:
- Oriented with laser path along the <110> axis
- Orientation accuracy to ± 5
- Entrance and exit faces flat and parallel, or at Brewster angle
- Standard parallelism 3-5 arcmin (tighter parallelism or a larger wedge upon request)
- Transmitted wavefront λ/6 on 50 mm-long crystals
- Dielectric coating available to protect polished surfaces from ambient moisture fogging
