Light-induced absorption in photorefractive strontium barium niobate [PDF]

open access: yes, 1994
Sr0.59Bao.41Nb2O6 and Sro.75Bao.25Nb2O6 exhibit an intensity-dependent absorption in the visible spectral range. We perform pump (green)-probe (red) measurements and find variation as high as 0.45 cm-' in the absorption coefficient, which depends ...
