LN (LiNbO3) Pockels Cells, also known as lithium niobate pockets cells, is a comprehensive and excellent pockels cells. The device is widely used in the fields of optical communication and optical waveguide technology. The product has the advantages of high electro-optical coefficient, non-hygroscopicity, a wide range of transparency, and good mechanical and physical properties, which can be applied in the fields of electro-optical modulators, modulation of laser beams outside the wave voltage of resonators. Lithium niobate crystals are one of the most commonly used materials for Q-switches and phase modulators due to their high electro-optical coefficient, non-hygroscopicity, good transmission up to 4.0 μm, and transverse mode operation. LiNbO3 pockels cells can be configured to operate at lower voltages than KD*P cells by applying an electric field laterally in the direction of light propagation. LiNbO3 pockels cells can support IR wavelength operation up to 4.0 μm and are also a good choice for low to medium power solid-state laser (Er: YAG, Ho: YAG, Tm: YAG pulsed lasers) applications. Also, LiNbO3 with MgO doping has a significantly higher damage threshold compared to conventional undoped LiNbO3.
