response time of two Cr-doped strontium barium niobate crystals with different dopant …

Two-beam coupling gain and speed of a Cr-doped strontium-barium niobate single crystal at
514.5 nm and 632.8 nm are measured to compare photorefractive origins and responses …

Photorefractive two-beam coupling gain and speed of Cr-doped potassium sodium strontium
barium niobate are measured as a function of crystal temperature. It is found that the …

Transition-metal dopants of chromium and rhodium altered the photorefractive properties of
