Product Description
Introduction :
Lanthanum gallium silicate crystal is referred to as LGS, which is a kind of multifunctional crystal with excellent performance. The dielectric, elastic and piezoelectric constants of LGS crystals are significantly higher than those of quartz, and the electromechanical coupling coefficient is 2 to 3 times that of quartz. It can be used to manufacture surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices. At the same time, LGS crystals can be used to make electro-optical Q switches, and the effect is comparable to DKDP crystal Q switches. The devices using LGS crystal as the material all have higher thermal stability.
Main Advantages :
- The electromechanical coupling coefficient is (3-4 times of quartz)
- High thermal stability
- The low equivalent series resistance ratio
