Abstract
We measured the quasi-phase-matching temperatures for SHG at 0.5321 µm with the oo-e, oo-o, and oe-o interactions in periodically poled 1mol% MgO doped stoichiometric lithium tantalate (MgO:PPSLT). The cross points of the temperature tuning curves of the QPM processes with different interactions exist around 80°C in this QPM device.
