Ti:Sapphire crystals are grown using the heat-exchange (Kyropoulos) method, allowing the production of large-diameter crystal boules up to 250 mm. Standard doping concentrations are 0.15 wt%, 0.25 wt%, 0.35 wt%, and 0.45 wt%, corresponding to absorption coefficients ranging from 0.6 cm⁻¹ to 7 cm⁻¹. This precise control of doping and absorption enables optimized performance for various ultrafast and high-power laser applications.

This product is suitable for use in leading industrial laser manufacturers, medical and aesthetic laser systems, and ultrafast, ultra-short, and ultra-intense laser research facilities worldwide. Utilizing advanced Ion-Assisted Deposition (IAD) coating technology, the Ti:Sapphire crystal achieves a high laser damage threshold. The standard coating configuration is AR/AR@532 nm + 750–850 nm, with other coating designs available upon request. The crystal can be fabricated in round, rectangular, or customized shapes, with standard end-face geometries including flat and Brewster-angle surfaces. To suppress parasitic oscillations and enhance thermal management, Ti:Sapphire crystals can be bonded with other materials, such as sapphire, around the edges. Both optical and non-optical surface bonding options are available depending on the application requirements.

A comprehensive set of strict quality control and inspection procedures ensures that each Ti:Sapphire crystal meets the required optical and performance standards, guaranteeing consistency and reliability in demanding laser environments.



1.20mW green laser is used to inspect the internal quality of the Ti:Sapphire crystal, checking for inclusions, bubbles, or other internal defects that may affect optical performance.

2.The surface quality of the Ti:Sapphire crystal is examined under a microscope to assess its surface smoothness and finish.

3.ZYGO laser interferometer is used to measure the crystal’s surface flatness, wavefront distortion, and parallelism, ensuring high optical precision and manufacturing quality.

4.UCM white-light interferometer (AM-7000) is employed to measure the surface roughness of the Ti:Sapphire crystal, ensuring nanometer-level surface precision and optical quality.

These comprehensive and precise inspection procedures effectively ensure the high-quality production and optical reliability of the Ti:Sapphire crystals.

Precautions: To ensure optimal performance, it is recommended to store and operate the crystal at 25 °C with a relative humidity of 40%–60%. If the crystal surface becomes contaminated, gently clean it with 99% or higher isopropyl alcohol and lint-free optical tissue. Avoid using rough fabrics, water, or abrasive cleaners, as these may damage the coating or crystal surface.
