LiNbO3 crystals and MgO:LiNbO3 crystals have become one of the most commonly used material for Q-switches and phase modulators for its high Electro-Optical coefficients, non-hygroscopicity, good transmission up to 4.0 µm and operation in transverse mode. With an electric field applied transverse to the direction of light propagation, LiNBO3 cells can be configured to operate at a lower voltage than comparable KD*P cells. LiNbO3 can also be a good choice for infrared wavelengths as long as 4.0 µm, it is good choice for Er:YAG, Ho:YAG and Tm:YAG medical lasers. With the MgO doped in LiNbO3, the damage threshold would be increased significantly.
Hangzhou Shalom EO offers the pockels cells made from LiNbO3 crystals and MgO:LiNbO3 crystals, with aperture size of 2.5mm to 9mm. The LiNbO3 and MgO:LiNbO3 crystals with Cr-Au electrode for electro-optical modulators or pockels cells are also offered.
