Abstract :
Summary form only given. The efficiency of nonlinear interactions based on periodically poled lithium niobate (PPLN) could benefit from laser action within the material. Towards this, periodic poling of LN doped in the bulk with neodymium (0.15% wt.) has been carried out, for the first time to our knowledge. The starting Z-cut crystals were about 600 /spl mu/m thick. After photoresist spin-coating and patterning, a standard liquid electrolyte fixture was used for electric field poling. The poling field was found to be lower than for undoped congruent LN (19 rather than 21 kV/mm), in agreement with previous experiments on Nd-indiffused LN.
