Abstract

We investigated angular tuning of quasi-phasematching (QPM) second-harmonic generation (SHG), in order to extend the tunable range of QPM and to combine the advantages of QPM and birefringence phase-matching. The direction of the input fundamental wave vector was detuned from the QPM grating vector along the crystallographic Zaxis of a periodically-poled lithium niobate (PPLN) crystal in the XY- and XZ-planes. A larger tuning range of SHG was obtained for the detuning in the XZ-plane, continuously shifting the QPM peak of the fundamental wavelength from 1524 to 1595 nm by changing the detuning angle from 0° (parallel to X-axis as conventional QPM) to 23.2°.
