Design of phase-reversed QPM structures for cascaded third and fourth harmonic generation in single quadratic crystal

The role of the ratio of the two design periods for phase reversed QPM structure is theoretically investigated. It is found that the efficiency of third and fourth harmonic generation strongly depends on this ratio. The results for third harmoic generation and fourth harmonic generation in LiTaO3, LiNbO3 and KTP are shown in graphical form.
