“…Experimental tests using green light from a cw argon ion laser 6,7 confirm that photorefractive damage is essentially absent in PPLN while being strongly present in SDLN. Although various different types of light-induced scattering due to photorefraction have been reported both in SDLN 8,9 and potassium niobate, 10,11 this is the first time to our knowledge that similar phenomena have been experimentally observed in PPLN crystals.…”

A new species of self-organized light-induced scattering, appearing only in bulk periodically poled lithium niobate, is reported. Clearly defined diffracted beams develop on exposure to 532 nm light from a frequency-doubled, Q-switched, and mode-locked Nd:YAG laser. The structure thus created also diffracts light at 1064 nm. The effect is strongly dependent on temperature, the polarization state of the light, and the period of domain reversal. It exhibits a sharply defined nonlinear threshold at which the far-field pattern of the diffracted light evolves rapidly.
