The YAG single crystal substrate must be matched to the target thin-film or device workflow to ensure material compatibility. Orientation, dimensions, thickness, polishing condition, and offcut details require confirmation prior to use.
- Material matching requirement: Confirm that the substrate material and crystal family match the target thin-film or device workflow to avoid incompatibility.
- Specification review requirement: Verify orientation, dimensions, thickness, polishing condition, offcut details, quantity, and any custom requirements before use.
What is the thermal conductivity of the YAG single crystal substrate and why is it critical for high-power laser applications?
The YAG substrate has a thermal conductivity of 143 W/(m·K) at 20°C, which is relatively high for an oxide crystal, enabling efficient heat dissipation in high-power laser and optical systems. This property, combined with a melting point of 1970°C and hardness of 8.5 Mohs, ensures thermal stability and resistance to thermal shock under intense pumping.
What is the lattice constant of the YAG substrate and how does it support epitaxial growth of rare-earth iron garnet films?
The YAG substrate has a cubic crystal structure with a lattice constant of a = 12.01 Å, which is closely lattice-matched to yttrium iron garnet (YIG) and other rare-earth iron garnets, making it an ideal template for epitaxial deposition in spintronic and magneto-optic devices. The crystal purity >99.999% minimizes misfit dislocations and ensures high-quality film growth.
What are the key optical transmission characteristics of the YAG substrate for use in the mid-infrared region?
The YAG substrate transmits from 250 nm to 5000 nm, with no obvious absorption in the 2000-3000 nm range, making it particularly suitable for mid-infrared optical components and laser host applications. The DSP surface finish ensures low scatter and high surface quality for direct optical use.
This YAG single crystal substrate (DSP finish) offers >99.999% purity, wide transmission from 250–5000 nm, and high thermal conductivity (143 W/(m·K)), making it suited for demanding optical and thin-film applications. However, the fixed 0.5 mm thickness and only two size options (10×10 and 20×20 mm) limit flexibility, and users must rigorously match crystal orientation and surface finish to their specific deposition or device workflow.
Positive
- Ultra-high purity and wide transmission: Crystal purity >99.999% and transmission range 250–5000 nm with no obvious absorption in the 2000–3000 nm band enable reliable performance in IR and visible optical applications.
- Excellent thermal management properties: Thermal conductivity of 143 W/(m·K) at 20°C and low thermal expansion coefficient of 6.9×10⁻⁶/°C (0–250°C) reduce thermal stress in high-power laser or photonic device environments.
Trade-offs
- Fixed thickness and limited size options: Only two dimensions (10×10×0.5 mm and 20×20×0.5 mm) are available; the 0.5 mm thickness is fixed, which may not accommodate workflows requiring thicker substrates or non-standard geometries.
- Requires exact material and specification matching: The substrate’s crystal family, orientation, and DSP surface finish must be precisely matched to the target thin-film or device process; buyers must confirm all parameters before ordering to avoid compatibility issues.
