“…Thoroughly understanding the two-wave coupling process in doped KNSBN crystals has significant importance in applications such as volume holographic storage, optical information process and optical switch [6][7][8][9] . Among the experimental studies of doped KNSBN crystals, most of the reports focused on the steady two-wave coupling properties, while the reports of the dynamic properties were mainly theoretical simulation [10][11][12][13] . In this paper, the dynamic two-wave coupling properties of extraordinarily polarized He-Ne 632.8nm laser beam in a Ce:KNSBN crystal were studied with a real-time data-acquisition system.…”

In this experiment, the dynamic two-wave coupling properties of extraordinarily polarized He-Ne 632.8nm laser beam in a Ce:KNSBN crystal were studied with a real-time data-acquisition system. The transmitted pump beam intensity I p ' and the transmitted signal beam intensity I s ' were recorded as a function of time. While the incident beams of two-wave coupling are both with extraordinary polarization, a great fanning will generate and it would affect the two-wave coupling dynamic properties. The dynamic evolution of two-wave coupling had great differences while the total incident beam intensity and the incident beam intensity ratio were different. The coupled-wave equations were modified according to the beam-fanning threshold phenomena and the experimental data. The theoretical calculation results obtained from the modified coupled-wave equations were agree with the experimental data very well.
