The second-harmonic generations (SHGs) of nanosecond pulses using first- and second-order quasi-phase matching (QPM) were realized in a two-dimensional periodically poled LiNbO3 with square lattice. Maximum conversion efficiency of 35% and 14% was achieved respectively at the fundamental wavelengths of 1.352 μm and 1.064 μm. In addition, the SHG of 1.064 μm picosecond laser using second-order QPM was also studied in this crystal. Based on the comparison between the SHGs excited by nanosecond and picosecond pulses, it may be concluded that if second-order QPM is used, the incident laser with higher peak power is necessary.
