LiNbO3 and MgO-LiNbO3 Nonlinear Crystal
LiNbO3 (Lithium Niobate) crystal is widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064 nm. Due to its large electro-optic and acousto-optic coefficients.
MgO:LiNbO3 (Magnesium Oxide Doped Lithium Niobate) crystal has similar effective nonlinear coefficients to pure LiNbO3 and exhibits higher optical damage threshold.
LiNbO3 Crystal Advantages:
1. Large Nonlinear Optical (NLO) Coefficients
2. High mechanical and chemical stability
3. Large electro-optic and acousto-optic coefficients
4. Wide transparency range
5. High optical homogeneity
LiNbO3 Crystal Applications:
1. Pockels Cells
2. Q-switches
3. Phase modulators
4. Surface acoustic wave(SAW) wafers
