LiNbO3 crystals and MgO:LiNbO3 crystals have become the most commonly used material for Q-switches and phase modulators for its high EO coefficients. 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 3.0 µm. Hangzhou Shalom EO offers the pockels cells made from LiNbO3 crystals and MgO:LiNbO3 crystals, with aperture size of 2.5mm to 9mm. 
Preferably for Er:YAG-, Ho:YAG-, Tm:YAG laser 
Wavelengths up to 3μm 
Brewster for laser with low amplification
