Product Description
3×3×20mm AR 1064nm Langasite Piezoelectric Crystal (La3Ga5SiO14)
Langasite crystal (La3Ga5SiO14, LGS) belongs to space group P321, point group 32, and represents a promising piezoelectric material for surface acoustic wave (SAW) and bulk acoustic wave (BAW) device fabrication. These devices can operate at temperatures up to 900℃ due to the crystal's exceptional thermal stability.
Manufacturing Excellence
Crystro's LGS crystals are grown using the Czochralski method, achieving maximum diameters of 60mm. We offer custom sizing and cutting directions to meet specific application requirements.
