LGS Crystal is a multifunctional crystal. The interaction between the electro-optical effect and optical rotation in the functional crystal has been considered and studied, and it can be used as an electro-optical crystal. The LGS electro-optical Q switch transmits 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-optical effect of the crystal to realize the Q-switching function of the LGS crystal. LGS electro-optic Q-switch is actually a new type of rotary electro-optic Q-switch. Due to the existence of the optical rotation effect, it can be used as a practical switching device to obtain a good Q-switching effect. LGS crystal broadens the exploration and discovery of new types of electro-optic crystals from optically active crystals.
