Ti doped sapphire windows’ properties

1. Optical Transparency: Ti:Sapphire windows exhibit excellent optical transparency across a broad spectral range, typically from ultraviolet (UV) to near-infrared (NIR) wavelengths. This transparency allows for efficient transmission of light, making them suitable for optical systems requiring high clarity.
2. Tunable Absorption and Emission: The titanium dopant in sapphire introduces energy levels within the crystal lattice, resulting in tunable absorption and emission characteristics. This property enables Ti:Sapphire windows to serve as active laser gain media, supporting widely tunable laser operation across the visible and near-infrared spectrum.
3. High Optical Quality: Ti:Sapphire windows are fabricated with high precision and undergo stringent quality control measures to ensure exceptional optical quality. This includes low levels of optical scattering and minimal absorption losses, allowing for high-performance optical systems.
4. High Damage Threshold: These windows exhibit a high resistance to optical damage, enabling them to withstand intense laser irradiation without significant degradation. This property is crucial for laser applications where high-power densities are involved, such as mode-locked lasers and amplifiers.
5. Chemical and Mechanical Stability: Sapphire, the host material for Ti doping, is renowned for its chemical and mechanical stability. Ti:Sapphire windows inherit these properties, making them resistant to chemical corrosion and mechanical stress, ensuring long-term durability in various operating environments.
6. Temperature Stability: Ti:Sapphire windows maintain their optical properties over a wide temperature range, making them suitable for use in both cryogenic and high-temperature applications.

Our customizable survices

Ti-doped sapphire windows are made using a specialized process that combines material science expertise with precision engineering. Here’s an outline of the production process, emphasizing the availability of customization services:

1. Material Synthesis: The process starts with the synthesis of the sapphire crystal, which is aluminum oxide (Al2O3) by nature. Titanium (Ti) ions are doped into the sapphire crystal structure during the crystal growth phase. This can be done using techniques such as the heat exchanger method (HEM) or the Czochralski process, where precise control over the temperature and atmosphere is crucial to ensure uniform distribution of titanium dopants.
2. Crystal Growth: The doped sapphire crystal is grown in a controlled environment. The growth process is monitored closely to maintain the quality of the crystal and ensure the correct concentration and distribution of the titanium dopant. The parameters of the crystal growth can be adjusted based on customer specifications to tailor the optical properties of the windows.
3. Fabrication: Once the crystal has been grown, it is cut into wafers or windows depending on the intended application. Advanced cutting techniques, such as laser cutting or precision mechanical cutting, are used to achieve high dimensional accuracy and surface finish.
4. Polishing and Finishing: The windows are then polished to achieve optical clarity and smoothness. The polishing process removes any surface defects and achieves the desired thickness and optical flatness. This stage can be highly customized to meet specific optical performance criteria, such as surface roughness or parallelism.
5. Coating: To enhance the performance of the Ti-doped sapphire windows, various optical coatings can be applied. These coatings can be anti-reflective, protective, or enhance other optical characteristics. The choice of coatings can be tailored to the specific requirements of the application, such as wavelength, durability, and resistance to environmental factors.
6. Quality Assurance and Testing: Each window undergoes rigorous testing to ensure it meets the required specifications. Optical and physical properties are tested, including transmission spectra, refractive index, and hardness. Custom testing protocols can be developed to align with specific customer requirements.
7. Customization and Support: Throughout the production process, there is a strong emphasis on customization. Customers can specify requirements for nearly every aspect of the window, including size, thickness, doping concentration, type of coatings, and more. Technical support is available to assist customers in selecting the right specifications for their applications.

This process highlights the ability to customize the Ti-doped sapphire windows to specific customer needs, making them suitable for a variety of high-performance optical applications.

Q&A

What is titanium doped sapphire?

Titanium-doped sapphire is an optically pumped, solid-state laser material with an indefinitely long stability and useful life. It is the most widely used crystal for wavelength tunable lasers. And it is a leading material in the field of femtosecond pulse lasers.

What is the use of Ti:sapphire laser?

These lasers are mainly used in scientific research because of their tunability and their ability to generate ultrashort pulses thanks to its broad light emission spectrum. Lasers based on Ti:sapphire were first constructed and invented in June 1982 by Peter Moulton at the MIT Lincoln Laboratory.

What is the principle of Ti:sapphire laser?

Light from the pump laser enters the Ti:sapphire laser housing and is reflected by a series of mirrors into a Ti:sapphire crystal in the laser cavity. Photons emitted by the doped sapphire crystal are guided through the resonator cavity by reflection from the surface of routing mirrors.
