Product Description
Good Optical Rotation Piezoelectric Effect LGS Crystals Electro-Optical Q-Switch Crystals
Introduction :
Langasite - Lanthanum Gallium Silicate, is a piezoelectric crystal of gallogermanate family .it is new and excellent piezoelectric crystal for BAW and SAW devices due to its excellent spectroscopic and acoustic characteristics.LGS also can be used as an electro-optic 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.
Main Advantages :
- Electromechanical coupling coefficient is (3-4 times of quartz)
- High thermal stability
- Low equivalent series resistance ratio
