Product Description
Product Overview
Mg-doped stoichiometric lithium tantalate (SLT) wafers are engineered for high-power frequency converter applications, offering exceptional thermal conductivity and precise optical properties. These wafers enable accurate quasi-phase-matched (QPM) second harmonic generation (SHG) and optical parametric oscillation (OPO) in demanding industrial environments.

Frequently Asked Questions
What are the products you mainly work on?
We are piezoelectric wafer specialists with over 30 years of experience. We were the first to work with Single Crystal Quartz in China and have expanded to LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS materials. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer complete customization services. Our experienced team can fabricate wafers to your exact specifications and provide technical guidance if needed. We also maintain standard wafer inventory for immediate delivery.
Can you deliver the goods via our courier agent?
Yes, we can ship using your preferred courier service (DHL, FedEx, UPS, etc.) via your account. We optimize packaging to minimize shipping costs while ensuring product safety. We also offer freight services with our established courier partnerships.
How can you guarantee we get what we want safely?
We use specialized packaging with buffer sponge and fragile labeling to protect these delicate wafers. Please follow our acceptance check procedure upon delivery. If damage occurs during transit, we provide replacements or refunds when proper documentation is provided.
Acceptance Check Procedure
- Handle products carefully upon receipt and inspect outer carton condition
- Document packaging condition with photos before removing products
- Open vacuum packaging in clean room environment only when ready for application
- If damage is found, photograph/video immediately without removing from packaging and contact us for resolution
