Abstract We derive new temperature dependent Sellmeier
equations for the extra-ordinary and ordinary refractive in-
dices of 0.5% MgO-doped stoichiometric LiTaO3 crystal.
The equations are based on quasi phase-matched frequency
conversion measurements, as well as on interferometric
measurements of the thermal expansion and thermal dis-
persion. These equations fit experimental data over wide
spectral ranges: 0.356 m for the extra-ordinary wave and
0.3753.75 m for the ordinary wave, from room tempera-
ture up to 200C. The nonlinear optical measurements set
lower-limit values for the d33, d22, and d24 elements of the
second-order susceptibility tensor (2) of 12.9, 1.54, and
0.46 pm/V, respectively. The interferometric measurements
