9 X 9 X25 mm LiNbO3 Crystal for EO Q Switch
LiNbO3 is also widely used as electro-optic modulators and O-switches for Nd: YAG, Nd: YLF and Ti:Sapphire lasers as well as modulators for fiber optics. The following table list the specifications of a typical LiNbO3 crystal used as Q-switch with transverse E-O modulation. The light propagates in z-axis. The electro-optic coefficients of LiNbO3 are: r33= 32 pm/V, r31= 10 pm/V, r22= 6.8 pm/V at at low frequency and r33= 31 pm/V, r31= 8.6 pm/V, r22= 3.4 pm/V at high electric frequency. The halfwave voltage: Vπ=λd/no3γc1, γc=(ne/no)3γ33-γ13.
Both pure LN and MgO doped LN (MgO:LN) crystals with gold coatings on side faces for electrodes are available
