Lithium Tantalate Substrate Applications

Optical Components: Used in high-end digital cameras for low-pass filters and holographic components in DVD pickup systems.
Telecommunications & Sensing: Applied in optical communications, optical switches, modulators, and gyro sensors for navigation systems.
Laser Technology: Enables wavelength conversion for blue and green laser generation using SHG techniques, essential for display, medical, and environmental applications.
Surface Acoustic Wave (SAW) Devices: Preferred for high-frequency SAW applications due to its high electromechanical coupling coefficient and low acoustic loss, with specific cuts like 36°Y, 42°Y, and X-cut.
Advanced SAW Applications: Blackened Lithium Tantalate wafers, produced through a reduction process, eliminate pyroelectric discharge, enhancing performance and reliability in high-frequency SAW devices.
