Abstract :
Field induced periodic poling is used to create >10 micron period structures in /spl sim/250 micron thick slabs of LiNbO/sub 3/. Third order quasi-phase-matched second harmonic blue light generation is demonstrated by free propagation of a 937 nm fundamental Gaussian beam in periodically poled LiNbO/sub 3/, with a conversion efficiency of 0.2%/W cm.<>
