Abstract

The experiment of a laser beam amplified by the other after both beams crossing a Ce-doped (0.1Wt%) strontium barium niobate (BaxSr1-xNbaO6 or SEN, x=0.48) crystal is reported and preliminary theoretical analysis is given. The density of mobile charges in Ce-SBN is calculated to be 4.5xl016pm-8 (at ambient temperature). The sign of mobile charges determined from the energy flow direction is positive. Couplings at different polarizations, different wavelengths and different doping amounts are compared.
