MgO:LiNbO3 Crystal

Compared with LiNbO3 crystal, MgO:LiNbO3 crystal (Magnesium Oxide Doped Lithium Niobate 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.
