Barium Nitrate Crystals, 30mm Length

Barium nitrate (Ba(NO3)2) is one of the leading crystals in solid-state Raman shifters. Ba(NO3)2 crystals have a moderately wide transparency range and a high damage threshold. The disadvantages of barium nitrate crystals are low thermal conductivity and high electro-optic coefficient, resulting in thermal lensing. Crystals are soft and hygroscopic, so they should be handled with care. We offer various specifications of Ba(NO3)2 crystals.
