  • Specifications

Barium nitrate crystal perfectly fits in as Raman shifter because of the following properties: crystals have high optical uniformity and broad transparency range from 0,33 μm to 1,8 μm, large Raman shift of 1047 cm-1 toward longer wavelengths and high conversion efficiency. Ba(NO3)2 crystals are optimal in the case of nanosecond and longer pulses, the Raman gain coefficient is higher compared with KGW and KYW crystals, though thermal lensing effect appears stronger in these crystals.
