Ti:Sapphire (Ti:Al₂O₃) Laser Crystals

Ti:Sapphire (Ti:Al₂O₃) is the most widely used tunable laser crystal, known for its exceptionally broad emission bandwidth and outstanding thermal/mechanical stability. With a tunable range from 650–1100 nm and strong absorption around 490 nm, Ti:Sapphire enables ultra-fast femtosecond lasers, high-energy amplifiers, biomedical imaging, spectroscopy, nonlinear optics, micromachining, and scientific research.

Our Ti:Sapphire crystals are grown using advanced Czochralski techniques with precise Ti³⁺ doping, ensuring high optical uniformity, excellent figure quality, and ultra-low scattering loss. Each piece is carefully cut, oriented, and optically polished to laser-grade specifications, making them ready for integration into commercial or custom laser systems.
