Optical properties of barium and strontium tungstate Raman crystals

摘要

Barium and strontium tungstate crystals were found to be very promising for developing crystalline Raman materials. UV and IR absorption were investigated in these crystals. The results on UV absorption are discussed in terms of Urbach rule. Our results prove that barium and strontium tungstate crystals can work efficiently in Raman lasers in visible and near IR from 264 nm to 5300 nm spectral regions.
