Magnesium Doped Lithium Niobate 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 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((λ i n um):
no2=4.8762+0.11554 / (λ2-0.04674 ) -0.033119 x λ2

ne2=4.5469+0.094779 / (λ2-0.04439) -0.026721 x λ2

Different dimensions of MgO:LiNbO3 with high quality are available from LASERMA. The AR coating is also available upon request.
