Ba(NO3)2 has the highest Raman gain coefficient among other SRS crystals. The gain coefficient affects the threshold for Raman laser. However, the thermal lensing is particularly strong in this material. This is indicated by the large value of dn/dT and low thermal conductivity.

 

Ba(NO3)2  crystals are used as Stimulated Raman Scattering (SRS) converters that provide non-linear conversion of laser radiation frequency due to Stimulated Raman Scattering effect. They can be used as frequency converters in tunable lasers for the extention of their tuning range.

 

Ba(NO3)2 crystals can also be used as a substitute for laser radiation frequency converters based on organic dye solution. This greatly improves the devices' performance characteristics.

 

Ba(NO3)2  crystals are free from bubbles and inclusions. The optical uniformity of Ba(NO3)2  crystals is comparable with the quality of barium and calcium fluoride crystals. Transmission band is from 0.35 µm up to 1.8 µm. The crystals can be used in the range from 1.8 µm up to 2.4 µm as optical filters.
