Product Description

LGS(La3Ga5SiO14 )is a multifunctional intraocular crystal that can be used as an electro-optic crystal after considering and studying the interaction between electro-optic effect and optical rotation in functional crystals. The LGS electro-optic Q switch passes light along the Z direction of the crystal and applies an electric field along the X direction, which can make full use of the lateral electro-optic effect of the crystal to realize the Q-switch function of the LGS crystal. The electro-optic Q-switch made by LGS is actually a new kind of rotation-electro-optical Q-switch. Because of the effect of optical rotation, it can be used as a practical switch and a good Q-modulation result can be obtained. LGS crystal widens the new direction of exploring and discovering new electro-optic crystals from optically active crystals.
