What is the spectral transmission range of the Atomfair AF-LN-10YDP lithium niobate substrate, and what wavelength applications does it support?
The substrate transmits from 0.4 to 2.90 μm, covering visible to near-infrared wavelengths suitable for frequency doubling, parametric oscillators, acousto-optic devices, and optical modulators as stated in the product overview.
How precise is the Y-128 orientation of this LiNbO3 substrate, and why is orientation tolerance critical for nonlinear optical devices?
The orientation tolerance is <0.5°, which is critical for maintaining phase-matching conditions in nonlinear optical processes such as second harmonic generation. The product specifies routine orientations including (0001), (11-20), and (10-10) with this tolerance.
Is this lithium niobate substrate MgO-doped to improve its optical damage threshold?
The product description mentions MgO doping as a general method to improve optical damage threshold, but this specific substrate (model AF-LN-10YDP) is not explicitly listed as MgO-doped. Confirmation with the manufacturer is recommended before assuming doping.
Assessment of Atomfair AF-LN-10YDP: a 10 × 10 × 0.5 mm Y-128 LiNbO3 crystal substrate with double-side anti-reflection finish, Czochralski growth, 0.4–2.90 µm transmission, < 0.5° orientation tolerance and < 5 Å polished surfaces; it fits nonlinear and electro-optic device workflows, with coating and MgO-doping status requiring confirmation ahead of high-fluence or coated-path use.
Positive
- Broad NLO transmission and high nonlinear coefficients: The Czochralski-grown trigonal LiNbO3 transmits from 0.4 to 2.90 µm and reports d33 = 34.45 pm/V, supporting parametric oscillators, frequency doubling, acousto-optic devices and optical modulators.
- Precision orientation and sub-5 Å polish: Y-128 orientation tolerance is < 0.5°, and routine double-side polishing yields < 5 Å surface roughness, providing a consistent optical interface for coating and device assembly.
Trade-offs
- Confirm AR coating and tolerance requirements: Atomfair's quotation note states that coating and tolerance requirements must be confirmed before quotation, so the specific AR wavelength range and acceptable orientation tolerance should be validated for the intended optical path.
- Verify MgO doping for high-fluence use: The material notes list MgO doping as a way to improve optical damage threshold; for high-fluence nonlinear operation, the selected substrate's doping status should be reviewed before deployment.
