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 g good crystal for optical parametric oscillators(OPOs) and amplifiers (OPAs),quasi-phase-matched doublers and integrated waveguide.

MgO:LiNbO₃ is characerized by:

• High damage threshold.

• Noncritical phase matching(NCPM)at room temperature

• Broad transparency range

• Excellent E-O and NLO properties

• Good mechanical and chemical properties

MgO:LiNbO₃ has similar effective nonlinear coefficients to pure LiNbO₃ Its Sellmeier equations (for 5mo1% MgO dopant) are:

n_o²=4.8762+0.11554 / (λ²-0.04674 ) -0.033119 x λ² (λ in μm)

n_o²=4.5469+0.094779 / (λ²-0.04439) -0.026721 x λ²
