Mg:LiNbO3
Crystal
description:
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 CASTECH. The AR coating is
also available upon request.
