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.

Key Features

  • Broad tunability: 650–1100 nm
  • High gain & strong fluorescence (~800 nm)
  • Exceptional thermal conductivity and mechanical strength
  • High damage threshold suitable for high-power femtosecond lasers
  • Uniform Ti³⁺ doping for consistent performance
  • Excellent optical homogeneity with low scatter and absorption
  • Precision orientation (typically <100> or <0001>)
  • Laser-grade polish: 10/5–20/10 scratch-dig (customer-customizable)
  • FOM Value>260(α532/α 808)

Frequently Asked Questions — Ti:Sapphire Crystal

What is a Ti:Sapphire crystal used for?
Ti:Sapphire is the most widely used tunable laser crystal for ultrafast femtosecond and picosecond lasers. Its extremely broad emission bandwidth (650–1100 nm) makes it ideal for scientific research, nonlinear optics, frequency combs, and biomedical imaging.
What Ti³⁺ doping concentrations do you offer?
We supply Ti:Sapphire crystals with Ti³⁺ doping levels from 0.03–0.25 wt%, suitable for oscillators, regenerative amplifiers, and multi-pass CPA systems. Custom doping levels are available upon request.
Do you offer custom dimensions and orientations?
Yes. We fabricate rods, slabs, wafers, and fully custom geometries. Available orientations include <100>, <0001>, and <10-12>. Simply send your drawing or specifications.
Can the crystals be AR or HR coated?
Yes. Laser-grade coatings are available, including:
  • AR @ 800 nm
  • Broadband AR (700–900 nm)
  • HR coatings for oscillator and amplifier cavities
All coatings are optimized for high damage threshold ultrafast operation.
What is the typical lead time?
Standard dimensions may be available from stock. Custom sizes typically require 2–3 weeks, including cutting, polishing, and optional coatings.
Do you offer academic or university discounts?
Yes. Universities and research institutions are eligible for special academic pricing. Please contact us for a formal quotation.
How should Ti:Sapphire crystals be handled and stored?
Crystals should be stored in a clean, dry environment. Avoid touching polished surfaces with bare hands. All crystals are shipped in protective optical packaging.
