Magnesium Oxide Doped Lithium Niobate Crystals(MgO:LiNbO3)
Compared with LiNbO3 crystal, MgO:LiNbO3 crystal exhibits its particular advantages for NCPM frequency doubling (SHG) of Nd:Lasers, mixing (SFG) and optical parametric oscillators (OPOs). The SHG efficiencies
of over 65% for pulsed Nd:YAG lasers and 45% for cw Nd:YAG lasers have been achieved in MgO:LiNbO3 crystals, respectively. MgO:LiNbO3 is also a good crystal for optical parametric oscillators (OPOs) and amplifiers (OPAs), quasi-phase-matched doublers and integrated waveguide.
MgO:LiNbO3 has similar effective nonlinear coefficients to pure LiNbO3. Its Sellmeier equations (for MgO dopant 7 mol%) are:
n2o (l) = 4.8762+0.11554/(l2 - 0.04674)-0.033119´ l2 ( l in mm)
n2o (l) = 4.5469+0.094779/(l2 - 0.04439)-0.026721´l2

ZnO:LiNbO3 crystal has the advantages of high damage threshold, non-critical phase-matching and good physical and chemical properties like MgO:LiNbO3. It has better optical quality and lower absorption loss than MgO:LiNbO3. Therefore, it is another candidate for frequency doublersmixers, OPOsOPAs, and quasi-phase-matched doublers and integrated optics.
Fe:LiNbO3 crystals is a kind of excellent photorefractive crystals for phase conjugations and holographic gratings and recording. Please refer to the photorefractive crystals for details.
