Application:
Optical parametric oscillation, difference frequency mixing to generate tunable infrared wavelengths, and second harmonic generation..
Lithium niobate is particularly effective for second harmonic generation of low power laser diodes in the 1.3 to 1.55 µm range.,
For infrared generation by difference frequency mixing, the peak power limit is considerably lower than for 1.064 µm, being about 40 MW/cm2
 
The Sellmeier equations (l in µm ):

The Fe:LiNbO3 and MgO:LiNbO3 crystals is available too. The MgO: LiNbO3 has similar effective nonlinear coefficients to pure LiNbO3. Its Sellmeier equations (for MgO dopant 7 mol%) are:
no2 = 4.8762+ 0.11554/(l2-0.04674)-0.033119l2
ne2 = 4.5469+ 0.094779/(l2-0.04439)-0.026721l2
