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 4.0 µm.
Hangzhou Shalom EO offers the polished and coated and Au-Cr electroded LiNbO3 crystals components for LiNbO3 pockels cells applications.
