Product Description
Pezoelectric Materials Lanthanum Gallium Silicate (LGS) Crystal For BAW And SAW Devices
Introduction :
Langasite - La3Ga5SiO14, 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 Appliaction :
- Electro-optic Q-switch
- SAW device /BAW device
- Sensor
- High power high repetition rate all solid state laser
- High and low temperature change laser
