Abstract
LiNbO3 crystals were periodically polled by applying eight 300-μs electric pulses at 25.6 kV/mm in the 230-μm-thick z-cut LiNbO3 with a 3.3-μm period Al grating pattern on the +c phase and an Al ground plane on the -c face. For the ultrashort pulses, SH efficiency is reduced significantly. The weak, nonphase-matched forward SH beam, which propagates along a path different from that for the backward SH beam because of the angled output facet, is reflected. The backward second harmonic generation (SHG) in periodically poled bulk LiNbO3 has the maximum conversion efficiency of approximately 0.02%.
